src/sys/dev/vx, branch release/8.2.0

MFC r207554:

2010-11-15T17:48:13+00:00

  Add new tunable 'net.link.ifqmaxlen' to set default send interface
  queue length. The default value for this parameter is 50, which is
  quite low for many of today's uses and the only way to modify this
  parameter right now is to edit if_var.h file. Also add read-only
  sysctl with the same name, so that it's possible to retrieve the
  current value.

MFp4: Network Adapter is redundant.

- vx_stop() requires the driver lock to be held.

2008-04-24T22:51:43+00:00

- Add some missing newlines to messages printed by vx_getlink().

- 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.

Fix another edge case I just noticed when committing the previous changes:

2005-10-06T18:41:31+00:00

If bus_setup_intr() fails, cleanup the ifnet setup in vx_attach() by
calling ether_ifdetach() and if_free().

Rototill vx(4), add locking, and mark MPSAFE:

2005-10-06T18:27:59+00:00

- Rename vxfoo() functions to vx_foo() to improve readability and
  consistency with other drivers.
- Prefix most the softc members with 'vx_' (the other members already had
  the prefix).
- Switch to using callout_init_mtx() and callout_*() rather than
  timeout() and untimeout().
- Add some missing calls to if_free() in some failure cases in vx_attach().
- Use if_printf() and remove the unit number from the softc.
- Remove uses of the 'register' keyword and spls.
- Add locked variants of vx_init() and vx_start().
- Add a mutex to the softc and lock it in various appropriate places.
- Setup the interrupt handler last during attach.

Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and

2005-08-09T10:20:02+00:00

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.
