[Intel-wired-lan] [PATCH net v1 1/2] igc: Fix Pause Frame Advertising

[Muhammad Husaini Zulkifli]

Fix Pause Frame Advertising when getting the advertisement via ethtool.
Remove setting the "advertising" bit in link_ksettings during default
case when tx and rx are in off state with Auto Negotiatiate off.

Below is the original output of advertisement link during tx and rx off:
Advertised pause frame use: Symmetric Receive-only

Expected output:
Advertised pause frame use: No
