From e308a5d806c852f56590ffdd3834d0df0cbed8d7 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 15 Jul 2008 00:13:44 -0700 Subject: netdev: Add netdev->addr_list_lock protection. Add netif_addr_{lock,unlock}{,_bh}() helpers. Use them to protect operations that operate on or read the network device unicast and multicast address lists. Also use them in cases where the code simply wants to block calls into the driver's ->set_rx_mode() and ->set_multicast_list() methods. Signed-off-by: David S.
