[dpdk-users] All links down with Chelsio T6 NICs

[Danushka Menikkumbura <danushka.menikkumbura@gmail.com>]

Hello,

When I run testpmd on a system with 2 two-port Chelsio T6 NICs, the link
status is down for all four ports. I use igb_uio as the kernel driver.
Below is my testpmd commandline and the startup log.

sudo ./build/app/dpdk-testpmd -l 0,1,2,5 -b 81:00.0 -- -i
