1b9990ba67 Fix len=-4 issues. 
When receiving a packet, if a receive buffer has length 0,
treat it the same way we treat a failed mapping.

Fix contributed by Wasabi Systems.

deb5def967 In the receive interrupt handler, compute the packet length before resetting 
m to point to the first buffer in the packet.  The bug would cause the
length of jumbo frames to be incorrect.

08c2f0bab5 In wm_stop(): 
- Clear the interrupt mask to ensure the device cannot assert its
   interrupt line.
 - Clear sc->sc_icr to ensure wm_intr() makes no attempt to service any
   currently pending or shared interrupt.

This should address the problem reported in both PR/29903 and PR/22493.
(wm(4) is susceptible to crashing in wm_intr() when the interface is downed)

f5a6c8bf2f Adjust csum_data usage; mask off the high 16 bits for L4 header stuff offset

83931ac682 The 8254x apparently doesn't respond well to I/O accesses at 0. Do not 
attempt to map the I/O BAR if it is 0.  This will have the side-effect
of causing the wm_reset() routine to fall back to memory BAR accesses
for those chips on which it would attempt I/O BAR accesses for the reset.

Also update the comments about why we attempt the I/O BAR accesses for
the reset in favor of the memory BAR accesses.

38f94c5d99 Don't bother caching the checksum context. Other drivers for this chip 
don't, and it seems as though doing it may cause some problems.

978214ebe8 If we have to do an m_pullup() when setting up offload parameters, 
make sure that the pullup was done into trailing space at the end of
the existing first-mbuf-in-chain.  If not, log an error and drop the
packet, because the mbuf chain no longer corresponds to the DMA map,
and we are already committed to transmitting the packet.

d1c33ede84 Work around another problem (that causes horrible performance) on the 82547: 
- Change the Tx:Rx on-chip RAM allocation ratio based on MTU:
  => 82547: > 8192 18K:22K, else 10K:30K
  => others: > 8192 24K:40K, else 16K:48K
  Values derived from Linux driver.
- On the 82547, keep track of how much of the Tx FIFO has been used.
  When in half-duplex mode, don't let packets wrap around the FIFO ring
  buffer, because that causes the chip to croak.  Detect this, stall the
  Tx queue, use a timer to wait for the packets to drain from the Tx FIFO,
  reset the internal FIFO pointers, and restart the Tx queue.  Basic
  algorithm (and some magic numbers) derived from FreeBSD and Linux drivers.
