    82599: KR-training over SFP direct attach?

    wayne roberts

      I have X520-DA2 cards, and was wondering if 802.3ap KR training is performed over the SFP+ cables (direct attach copper).


      In the 82599 datasheet (section it seems to imply that 802.3ap training is performed, as described in section 72.6.10 of 802.3ap-2007.

      I wish to confirm this is true.


      It would seem to make sense that the same performance optimizations for backplane KR would apply to direct attach (SFP+) copper cables (i hope?)
