Memset our hardware SCB to 0 so that untouched

Use the same SCB transfer size for all chip types

structure, which is new to the 82550 and 82551, is used to transmit
a packet. This appears to fix the packet truncation problem that was
observed when using 82550-based fxp cards to transmit ICMP or fragmented
UDP packets of certain lengths which only had one to three bytes in the
second and final mbuf of the packet. This matches a note in the "Intel
8255x 10/100 Mbps Ethernet Controller Family Open Source Software Developer
Manual", which says that the hardware parse bit should be set when sending
these types of packets.
There have also been unconfirmed reports of similar problems when
transmitting TCP packets, which should not be affected by the above
mentioned change because the hardware parse bit was already being set
if the stack requested hardware checksumming of the packet. If the
problem remains, the use of the IPCB structure can be disabled to
cause the driver to fall back to using the older 82559 interface with
82550-based cards by setting
hint.fxp.UNIT_NUMBER.ipcbxmit_disable
to a non-zero value at boot time, or using kenv to set this variable
before using kldload to load the fxp driver.

set on realtek cards, but they work without it (and don't work with
it). The standard seems to imply that this is just a hint anyway, so
this should be harmless. It doesn't appear to be set on any other
cardbus cards that I have (or have seen).
This should make the rl based CardBus cards work again. I've been
running it for about a month now.

on if_fxp cards. When flow control is enabled, if the operating system
doesn't acknowledge the packet buffer filling, the card will begin to
generate ethernet quench packets, but appears to get into a feedback
loop of some sort, hosing local switches. This is a temporary workaround
for 5.1: the ability to configure flow control should probably be
exposed by some or another management interface on ethernet link layer
devices.

- Fix compilation without GEM_DEBUG.
- Do not #define GEM_DEBUG by default; it adds overhead (due to bzero()ing
RX space) and is not needed any more, since the driver is quite stable
now.
- Fix watchdog timeouts when failing to load TX packets.
- Do not forcibly limit the number of descriptors used for a packet to
GEM_NTXSEGS, by passing this number to bus_dma_tag_create(). There is
no requirement for a limit any lower than the total number of
available descriptors, and the present limit caused network problems
due to mbuf chains requiring more descriptors.
GEM_NTXSEGS is still used to estimate the interrupt window size, for
which we just need an estimate.
