From 2f5cb43406d0b29b96248f5328a14a6f6abf8ae6 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Wed, 30 Dec 2009 08:23:30 +0000 Subject: phylib: Properly reinitialize PHYs after hibernation Since hibernation assumes power loss, we should fully reinitialize PHYs (including platform fixups), as if PHYs were just attached. This patch factors phy_init_hw() out of phy_attach_direct(), then converts mdio_bus to dev_pm_ops and adds an appropriate restore() callback. Signed-off-by: Anton Vorontsov Signed-off-by: David S.

The mc_loop flag is present in the family specific part of the socket (e.g. the IPv4 or IPv4 specific part). setsockopt sets the inner family mc_loop flag. When the packet is pushed through the L3 tunnel it will eventually be processed by the outer family which if different will check the flag in a different part of the socket then it was set.
