da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * Locking strategy in this file is explained as follows:
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * - A global lock(vswp->mac_lock) is used to protect the
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * MAC calls that deal with entire device. That is, the
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * operations that deal with mac_handle which include
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * mac_open()/close() and mac_client_open().
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * - A per port/interface RW lock(maccl_rwlock) is used protect
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * the operations that deal with the MAC client.
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * When both mac_lock and maccl_rwlock need to be held, the
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * mac_lock need be acquired first and then maccl_rwlock. That is,
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * mac_lock---->maccl_rwlock
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * The 'mca_lock' that protects the mcast list is also acquired
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * within the context of maccl_rwlock. The hierarchy for this
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * one is as below:
da14cebe459d3275048785f25bd869cb09b5307fEric Cheng * maccl_rwlock---->mca_lock
