ixgbe: Configure advertised speeds correctly for KR/KX backplane
[ Upstream commit 54f6d4c42451dbd2cc7e0f0bd8fc3eddcab511fe ]
This patch ensures that the advertised link speeds are configured
for X553 KR/KX backplane. Without this patch the link remains at
1G when resuming from low power after being downshifted by LPLU.
