Hi,
after upgrading from ixgbe 5.7.1 to 5.8.1, my X550-T2 NICs can no
longer auto-negotiate a link with 2.5Gb/s or 5GB/s.
I diffed the code and noticed that in src/ixgbe_phy.c the following
lines were removed:
case ixgbe_mac_X550:
hw->phy.speeds_supported |= IXGBE_LINK_SPEED_2_5GB_FULL;
hw->phy.speeds_supported |= IXGBE_LINK_SPEED_5GB_FULL;
break;
Indeed, when reverting just this change, ixgbe 5.8.1 successfully
brings up links with 2.5Gb/s and 5 Gb/s again.
As the change has not been mentioned in the release notes as an
intentional feature removal, I wonder if it's an accidental
regression?
Kind regards,
Philipp
