Bugfix for the Realtek PHY driver... an RTL8201L standalone PHY
needs different handling than the integrated ones in terms of
speed detection. There was a bogus test based on the parent
device driver name string controlling which speed register to
query. That test began failing when the rl driver was split into
separate rl and re drivers some time ago. Apparently nobody ever
noticed because the buggy code only executes if NWAY negotiation
failed. Since we happen to be testing with an ancient dumb hub
rather than a modern switch, we found it.
To fix it all, have the attach() routine notice whether we're
dealing with an integrated PHY or an RTL8201L and store that info
in a struct accessible to the status() routine that needs to know
which register to query.
I touched up the fixes because they were relative to RELENG_6 and to
bring a few nits into line with style(9).
