Subject: Network do not works with linux >= 6.1.2. Issue bisected to
"425c9bd06b7a70796d880828d15c11321bdfb76d" (RDMA/irdma: Report the correct
link speed)
Hello,
I would like to report a >= 6.1.2 some network regression (looks like
NIC us not UP) on our Dell R7525 servers with E810 NICs. The issue was
observed after I updated 6.1.0 to 6.1.2 or newer (tested up to newest
6.1.4-rc1). The system is not accesible and all services are in D
state after each reboot.

I bisected the issue to a commit
"425c9bd06b7a70796d880828d15c11321bdfb76d" (RDMA/irdma: Report the
correct link speed). Reverting this commit in my kernel build "fix"
the issue and the server has a working network again.
