Some EHCI chips from VIA / ATI seem to trigger interrupts before writing back
the qTD status, or miss signalling occasionally under heavy load. If the host
machine is too fast, we can miss transaction completion - when we scan the
active list the transaction still seems to be active. This generally exhibits
itself as a umass stall that never recovers.
We work around this behaviour by setting up this callback after any softintr
that completes with transactions still pending, giving us another chance to
check for completion after the writeback has taken place

- fix a memory leak on the USB backend
- fix invalid pointer computations (in one case memory outside the allocated
area was written in LibUSB v1.0)
- make sure memory is always initialised, also in failing cases
- add missing functions from v1.0.4

Revision 1.158 says only lower ten bits of
BGE_RXLP_LOCSTAT_IFIN_DROPS register is valid. For BCM5761 case it
seems the controller maintains 16bits value for the register.
However 16bits are still too small to count all dropped packets
happened in a second. To get a correct counter we have to read the
register in bge_rxeof() which would be too expensive.

client just before queuing a request for the connection. The
code already had a check for the connection being shut down
while the request was queued, but not one for the shut down
having been initiated by the server before the request was
in the queue. This appears to fix the problem of slow reconnects
against an NFS server that drops inactive connections reported
by Olaf Seibert, but does not fix the case
where the FreeBSD client generates RST segments at about the
same time as ACKs. This is still a problem that is being
investigated. This patch does not cause a regression for this
case.

These chips are also supported by ata(4). Some vendors, like Supermicro,
are using same chips without providing HPT RAID BIOS.

Since we always access BGE_RXLP_LOCSTAT_IFIN_DROPS register in
bge_tick, remove useless code protected by #ifdef notyet.

It is valid for an on-disk GPT header to report a header size which is
greater than 92 bytes. Previously, we would read in the sector and copy
only the 92 bytes that we know how to deal with before calculating the
checksum for comparison. This meant that when we did the checksum, we
overshot the buffer and took in random memory, so the checksum would fail.
We now determine the size of the header and allocate enough space to
preserve the entire on-disk contents. This allows us to be correctly
calculate the checksum and be able to modify and write the header back
to the disk, while preserving data that we might not understand.

Introduce two spare dma maps for standard buffer and jumbo buffer

dma map sync and unloading operation until we know dma map for new
buffer is successfully loaded. This change saves unnecessary dma

previously advertised a zero-sized window. The current code requires the
receive window to be exactly zero for this to kick in. If window scaling is
enabled and the window is smaller than the scale, then the effective window
that is advertised is zero. However, in that case the zero-sized window
handling is not enabled because the window is not exactly zero. The fix
changes the code to check the raw window value against zero.
