[PATCH 5/8] net/ncsi: Enable AEN on active channel

[Gavin Shan]

NCSI AEN packets are transmitted by far end to notify the network
status change. We had the wrong assumption that the functionality
is enabled in far end by default.

This transmits a AEN enablement packet when configuring the active
channel.
