Serdes link comes up very fast.  The clause 37 autoneg involves going
through a few states and exchanging base pages and optional next pages.
Each state completes in 10 msec, so the whole autoneg should complete in
roughly 100 msec or so.  But because it is done in software for these
older cards, it can take much longer because it can get out-of-sync.
