Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/

2009-06-26T11:45:06+00:00

IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs.  This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.

For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.

  from the softc.
- Rework the watchdog timer to match other NIC drivers:
  - Start a timer in fe_init() that runs once a second and checks a counter
    in the softc that is identical to the deprecated 'if_timer'.
  - Just adjust the softc tx timeout value when sending packets instead of
    scheduling the timer.
- Use IFQ_SET_MAXLEN().

- Add a mutex to the softc to protect the softc and device hardware.
- Don't leak bus resources if if_alloc() fails during attach.
- Setup the interrupt handler after calling ether_ifattach().
- Use a private timer to manage the transmit watchdog.

- Store pointer to the link-level address right in "struct ifnet"

2005-11-11T16:04:59+00:00

  rather than in ifindex_table[]; all (except one) accesses are
  through ifp anyway.  IF_LLADDR() works faster, and all (except
  one) ifaddr_byindex() users were converted to use ifp->if_addr.

- Stop storing a (pointer to) Ethernet address in "struct arpcom",
  and drop the IFP2ENADDR() macro; all users have been converted
  to use IF_LLADDR() instead.

IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.
