When packets are received on the error queue, this function under
net_ratelimit():

netif_err(priv, hw, net_dev, "Err FD status = 0x%08x\n");

does not get printed. Instead we only see:

[ 3658.845592] net_ratelimit: 244 callbacks suppressed
[ 3663.969535] net_ratelimit: 230 callbacks suppressed
[ 3669.085478] net_ratelimit: 228 callbacks suppressed

Enabling NETIF_MSG_HW fixes this issue, and we can see some information
about the frame descriptors of packets.

I'm sorry for failing to mention the target tree in the email subject.
This is directed towards net-next.
