4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync EFI ARP Protocol Definition
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The EFI ARP Service Binding Protocol is used to locate EFI
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync ARP Protocol drivers to create and destroy child of the
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync driver to communicate with other host using ARP protocol.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The EFI ARP Protocol provides services to map IP network
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync address to hardware address used by a data link protocol.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This function is used to assign a station address to the ARP cache for this instance
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync of the ARP driver.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Each ARP instance has one station address. The EFI_ARP_PROTOCOL driver will
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync respond to ARP requests that match this registered station address. A call to
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync this function with the ConfigData field set to NULL will reset this ARP instance.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Once a protocol type and station address have been assigned to this ARP instance,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync all the following ARP functions will use this information. Attempting to change
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync the protocol type or station address to a configured ARP instance will result in errors.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param This The pointer to the EFI_ARP_PROTOCOL instance.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param ConfigData The pointer to the EFI_ARP_CONFIG_DATA structure.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_SUCCESS The new station address was successfully
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync registered.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_INVALID_PARAMETER One or more of the following conditions is TRUE:
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync * This is NULL.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync * SwAddressLength is zero when ConfigData is not NULL.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync * StationAddress is NULL when ConfigData is not NULL.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_ACCESS_DENIED The SwAddressType, SwAddressLength, or
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync StationAddress is different from the one that is
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync already registered.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This function is used to insert entries into the ARP cache.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync ARP cache entries are typically inserted and updated by network protocol drivers
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync as network traffic is processed. Most ARP cache entries will time out and be
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync deleted if the network traffic stops. ARP cache entries that were inserted
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync by the Add() function may be static (will not time out) or dynamic (will time out).
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Default ARP cache timeout values are not covered in most network protocol
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync specifications (although RFC 1122 comes pretty close) and will only be
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync discussed in general terms in this specification. The timeout values that are
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync used in the EFI Sample Implementation should be used only as a guideline.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Final product implementations of the EFI network stack should be tuned for
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync their expected network environments.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param This Pointer to the EFI_ARP_PROTOCOL instance.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param DenyFlag Set to TRUE if this entry is a deny entry. Set to
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync FALSE if this entry is a normal entry.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param TargetSwAddress Pointer to a protocol address to add (or deny).
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync May be set to NULL if DenyFlag is TRUE.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param TargetHwAddress Pointer to a hardware address to add (or deny).
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync May be set to NULL if DenyFlag is TRUE.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param TimeoutValue Time in 100-ns units that this entry will remain
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync in the ARP cache. A value of zero means that the
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync entry is permanent. A nonzero value will override
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync the one given by Configure() if the entry to be
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync added is a dynamic entry.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Overwrite If TRUE, the matching cache entry will be
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync overwritten with the supplied parameters. If
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync FALSE, EFI_ACCESS_DENIED is returned if the
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync corresponding cache entry already exists.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_SUCCESS The entry has been added or updated.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_INVALID_PARAMETER One or more of the following conditions is TRUE:

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_OUT_OF_RESOURCES The new ARP cache entry could not be allocated.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_ACCESS_DENIED The ARP cache entry already exists and Overwrite
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync is not true.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_NOT_STARTED The ARP driver instance has not been configured.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This function searches the ARP cache for matching entries and allocates a buffer into
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync which those entries are copied.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The first part of the allocated buffer is EFI_ARP_FIND_DATA, following which
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync are protocol address pairs and hardware address pairs.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync When finding a specific protocol address (BySwAddress is TRUE and AddressBuffer
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync is not NULL), the ARP cache timeout for the found entry is reset if Refresh is
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync set to TRUE. If the found ARP cache entry is a permanent entry, it is not
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync affected by Refresh.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param This The pointer to the EFI_ARP_PROTOCOL instance.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_INVALID_PARAMETER One or more of the following conditions is TRUE:
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This is NULL. TargetHwAddress is NULL.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_ACCESS_DENIED The requested address is not present in the normal
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync ARP cache but is present in the deny address list.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Outgoing traffic to that address is forbidden.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_NOT_STARTED The ARP driver instance has not been configured.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_NOT_READY The request has been started and is not finished.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This function aborts the previous ARP request (identified by This, TargetSwAddress
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync and ResolvedEvent) that is issued by EFI_ARP_PROTOCOL.Request().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync If the request is in the internal ARP request queue, the request is aborted
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync immediately and its ResolvedEvent is signaled. Only an asynchronous address
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync request needs to be canceled. If TargeSwAddress and ResolveEvent are both
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync NULL, all the pending asynchronous requests that have been issued by This
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync instance will be cancelled and their corresponding events will be signaled.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param This The pointer to the EFI_ARP_PROTOCOL instance.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param TargetSwAddress The pointer to the protocol address in previous
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync request session.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param ResolvedEvent Pointer to the event that is used as the
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync notification event in previous request session.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_SUCCESS The pending request session(s) is/are aborted and
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync corresponding event(s) is/are signaled.
