Hi,

With rc1 my T62100-LP-CR no longer functions correctly. Everything
appears fine but the link never goes into the UP state. I have one peer
with an older (functioning) kernel and the other peer on rc1.

I've bisected to find this is the offending commit:

3bb4858fd: cxgb4: avoid disabling FEC by default

I've also attached a bisect log.

Let me know if you need anything else.

Thanks,

Logan
