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

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

[Danushka Menikkumbura]

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

Please run the command "show port summary all"

Thank you for reporting the issue. I have forwarded the reported issue
to Chelsio support team and we are looking into it.

Thank you for adding me to the thread Thomas.
