This is sensible advice.

Sure, it shouldn't be necessary.  The drivers/NICs shouldn't be doing
this in the first place.

But shit happens.

And there are many, many times when a wedged driver can be resurrected
by a down/up or a rmmod/insmod.  This means that the driver _could_ have
automtically recovered in tx_timeout, but it simply did not do so.

Can anyone suggest a reason why we _shouldn't_ simply reset the NIC to
the utmost possible extent in tx_timeout?  Restart media selection,
reinitialise ring buffers, etc, etc?
