Sathya Perla b71724147e be2net: replace polling with sleeping in the FW completion path ... The ndo_set_rx_mode() and ndo_add/del_vxlan_port() calls may be called with BHs disabled. The driver currently issues the required cmds to the FW in these contexts and polls on completions from the FW, while BHs remain disabled. This can cause either packet loss or packet reception to be delayed on that CPU. This patch defers processing of the above cmds to a separate workqueue. With this change, FW cmds are now issued only in process context. Now that the FW cmds are issued only in process context, they can sleep waiting for a completion instead of polling. All the spin_lock_bh(mcc_lock) calls are now replaced with mutex calls. Also a new rx_filter_lock is now needed to protect the RX filtering fields like vids[] between be_vlan_add/rem_vid() and __be_set_rx_mode() contexts.
