I have been debugging the usb problems some more. Your were
right in your assumption (thanks for the pointer) about lack
of calls to bus_dmamap_sync(). In usbdi.c bus_dmamap_sync()
does get used for transfers that move data from PC to USB and
it is used for transfers that move data from USB to PC. But
someone forgot that control transfers consist of possibly two
data chunks : the request itself and optionally a buffer of
data that should be transfered to or from the USB device. On
requests to the control endpoint without additional data
bus_dmamap_sync() didn't get called. For some reason my first
tests with umass worked (due to enough cache poisening I
guess). The attached patch adds a call to bus_dmamap_sync()
to usbdi.c and now all devices I have tried work out of the
box. I have successfully transfered large files using the
if_axe driver and I have mounted several different umass
devices.

marked INP_DROPPED or INP_TIMEWAIT:
o return ECONNRESET instead of EINVAL for close, disconnect, shutdown,
rcvd, rcvoob, and send operations
o return ECONNABORTED instead of EINVAL for accept
These changes should reduce confusion in applications since EINVAL is
normally interpreted to mean an invalid file descriptor. This change
does not conflict with POSIX or other standards I checked. The return
of EINVAL has always been possible but rare; it's become more common
with recent changes to the socket/inpcb handling and with finer-grained
locking and preemption.
Note: there are other instances of EINVAL for this state that were
left unchanged; they should be reviewed.

2) Reduce the acquisitions of the Giant lock in the nfs_socket.c paths significantly.
- We don't need to acquire Giant before tsleeping on lbolt anymore,
since jhb specialcased lbolt handling in msleep.
- nfs_up() needs to acquire Giant only if printing the "server up"
message.
- nfs_timer() held Giant for the duration of the NFS timer processing,
just because the printing of the message in nfs_down() needed it
(and we acquire other locks in nfs_timer()). The acquisition of
Giant is moved down into nfs_down() now, reducing the time Giant is
held in that path.

processing are forced to toggle this functionality when the card
is put in and out of promiscuous mode. The main reason for this
is because the hardware strips the VLAN tag, making it impossible
for the tag information to show up in network diagnostic tools like
tcpdump(1).
This change introduces ether_vlan_mtap(), which is called if the
mbuf has M_VLANTAG set. VLAN information is extracted from the
mbuf and inserted into a stack allocated ether vlan header which
is then inserted through the bpf machinery via bpf_mtap2(). The
original mbuf's data pointer and lengths are temporarily adjusted
to eliminate the original Ethernet header for the duration of the
tap operation. This should have no long term effects on the mbuf.
Also, define a new macro, ETHER_BPF_MTAP which should be used
by drivers which support hardware offload of VLAN tag processing.
The fixes for the relevant drivers will follow shortly.
