Subject: [PATCH] net/cxgbe: avoid sending link params change from VF
VFs are not allowed to change physical link params when a port
module change is detected. The firmware already returns appropriate
permission error when VF tries to change physical link params. But,
make sure to avoid sending the command to firmware from VF in the
first place and prevent flooding firmware debug logs with permission
errors.
Fixes: a83041b1e998 ("net/cxgbe: rework and simplify link handling")
