08bbc8e180 Fix typo in HW checksum code -- check for TCP & UDP HW checksumming being 
enabled rather than TCP twice.

37ea29ba5a Perform a s/w checksum for packets that are not the same length as the length 
field of the IP header (ip->ip-len) indicates they should be.  This handles
the case where an ethernet frame has been padded to meet the minimum ethernet
frame length or erroneously (my cisco switch unnecessarily adds 4 bytes to its
SYN).  This padding will be included in the hardware checksum and may be
non-zero, thus making it incorrect.
Also, clear csum_flags when we want a s/w checksum, since we may have started
down the h/w checksum path and determined that it was not usable.

While here, clean-up a few WS nits and ifdef INET the hardware checksum code.

e9818f5b5e When adding/deleting multicast addresses, only whack the address

9efbbebf3a do not reset the chip (and subsequently the phy) when unnecessary; that is, 
for address changes, multicast filter changes, or adjusting promiscuous mode.
Fixes resetting the phy for things like start/stopping tcpdump.

324c47457d Since we have to select one of the two possible PHYs when configuring 
the MIF Configuration Register PHY_Select, there is no use in pretending
we could talk to both at the MII interface layer.

If both PHY are reported to be present, prefer the external one.

Remember this selection and enforce it in hme_mii_{read,write}reg.
This fixes problems with one of the dual hmes in Netra T1s.

From OpenBSD.

one (instance zero), if there is more than one PHY attached.

fc96443d15 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.
