Reject ioctl commands for FLSHGCHR and FLSHPCHR if the size is greater
than sc->areq.  This is a bounds check to ensure we're not just cramming
arbitrarily sized nonsense into the driver and overflowing the heap.

  Fix several panics when initialization of an ISA or PC-CARD device fails:

  o  Assign sc->an_dev in an_probe() (which isn't really a probe function in
     the standard newbus sense) as we may need it for printing errors.
  o  Use device_printf() rather than if_printf() in an_reset() - this is
     called from an_probe() long before the ifp structure is initialised
     in an_attach().
  o  Initialize the ifp structure early in an_attach() as we use if_printf()
     in cases where allocation of descriptors etc fails.

Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI

2013-08-12T23:30:01+00:00

command register.  The lazy BAR allocation code in FreeBSD sometimes
disables this bit when it detects a range conflict, and will re-enable
it on demand when a driver allocates the BAR.  Thus, the bit is no longer
a reliable indication of capability, and should not be checked.  This
results in the elimination of a lot of code from drivers, and also gives
the opportunity to simplify a lot of drivers to use a helper API to set
the busmaster enable bit.

This changes fixes some recent reports of disk controllers and their
associated drives/enclosures disappearing during boot.

Fix some net80211 enum nits:

2011-12-17T10:23:17+00:00

- ic_vap_create() uses an ieee80211_opmode argument
- ieee80211_rate2media() takes an ieee80211_phymode argument
- ieee80211_plcp2rate() takes an ieee80211_phytype argument
- cast to enum ieee80211_protmode and ieee80211_roamingmode to silence
  compiler warnings

Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.

2011-11-07T15:43:11+00:00

The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

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.
