[PATCH net 1/3] bnx2x: Fix port identification for the 84834

[Yaniv Rosner]

Fix the "ethtool -p" for boards with BCM84834, by using LED4 of the PHY 
to toggle the link LED while keeping interrupt disabled to avoid NIG attentions,
and at the end restore NIG to previous state.

[PATCH net 2/3] bnx2x: Fix KR2 link

[Yaniv Rosner]

Fix KR2 link down problem after reboot when link speed is reconfigured via ethtool.
Since 1G/10G support link speed were missing by default, 1G/10G link speed were
not advertised.

[PATCH net 3/3] bnx2x: Fix KR2 work-around condition

Fix condition typo for running KR2 work-around though it doesn't have 
real effect since the typo bits matched by chance.
