number of queued packets in watchdog timeout handler. If there are
no queued packets just print a informational message and return
without resetting controller. Also fix to invoke correct Tx
completion handler as 3C905B needs different handler.
Previously it used to clear the flag only when the transmit queue
is empty which may slow down Tx performance.
While I'm here check whether driver is running and whether we can
queue more packets in if_start handler. This fixes occasional
watchdog timeouts.

checksum offload frames. Software workaround used for broken
controllers(RTL8169, RTL8168, RTL8168B) seem to cause watchdog
timeouts on RTL8139C+.
Introduce a new flag RL_FLAG_AUTOPAD to mark automatic padding
feature of controller and set it for RTL8139C+ and controllers that
use new descriptor format. This fixes watchdog timeouts seen on
RTL8139C+.

- Display additional PCI express details including the negotiated and max

1. Leave the RX interrupt routine if there is no mbuf available.
2. Properly initialize and track tx_desc_used_count counter so as not to
leak mbuf while traversing used descriptors.

- Remove redundant softc members for RIDs.
- Change some softc members to be unsigned where more appropriate.
- Add some missing const.
- Remove support for mmap(2)'ing VGA I/O as it was broken [1] and
not required by X.Org anyway.
- Fix some confusion between bus, physical and virtual addresses
which mostly consisted in using members of struct video_adapter
inappropriately but wasn't fatal except for the regular framebuffer
mmap(2)'ing.
- Remove redundant bzero(9)'ing of the softc.
- Don't map the framebuffer twice in case the firmware has already
mapped it as besides wasting resources this isn't possible with
all MMUs. This is a bit tricky as a) just because the firmware
provides a property with a virtual address doesn't mean it's
actually mapped (but typically is when the framebuffer is the
console) and b) the firmware doesn't necessarily map the it with
the same byteorder as we do. This make machfb(4) work on machines
with cheetah-class MMUs (including X.Org).

pci_add_map(), pci_alloc_map(), and pci_delete_resource() now use these

- Just pass the device_t for the new PCI device to various routines instead
of passing the device, bus, slot, and function.

Remote host can advertise smaller MSS than that of sender so upper
stack might have adjusted the MSS which in turn generates IP
packets that are less size than that of interface MTU.

Otherwise we fall off the net.

o Enable the TX_PLL when we enable TX. This is harmless on most

could be had by managing this better, but for now it gets my card
working.
