When a net device goes down or when the bnx2i driver is unloaded,
the code was not generating the ISCSI_KEVENT_IF_DOWN message
properly and this could cause the userspace driver to crash.
This is fixed by sending the message properly in the shutdown path.
cnic_uio_stop() is also added to send the message when bnx2i is
unregistering.

Some 8168 are unable to WoL when receiving is not enabled (plain
old 8169 do not seem to care).
It is not exactly pretty to leave the receiver enabled but we
should now enable DMA late enough for it to be safe. Some late
stage boot failure due to pxe and friends may benefit from the
delayed enabling of bus-mastering as well.

This update cleans up the receive address register initialization. The
main purpose of this is to clean out some redundancy that was introduced
due to having multiple ways of setting the receive address registers.
Instead of having a specialized function to set one register and one to set
all of them it makes more sense to just go through the list calling the
function that is needed to set the individual registers.
