I compiled and installed the out of tree ixgbe driver and set the option in /etc/modprobe.d/ixgbe.conf. dmesg shows all eight "allow_unsupported_sfp enabled" messages but the last four ports still error out with the unsupported SFP message when running the tests. Before I start arbitrarily trying to patch out parts of the SFP verification code in ixgbe, are there any other tips I should know? Alex Forster
