bnxt driver spams logfiles with

[  541.003065] bnxt_en 0000:5d:00.1 eth5: Link speed -1 no longer supported

if a direct attached cable (DAC) is plugged into the bnxt card and is
unplugged on the other side. This patch removes the code printing this
message, since it doesn't provide any useful information.

This is supposed to provide useful information to the user under some
conditions.  In your particular situation, it is not useful since the
speed is -1.  Let me try to modify this code a bit to reduce the spam.
I will post a revised patch in the next 2 hours.

Thanks.
