Nuke all occurrences of usbd_abort_pipe() if it gets called right
before usbd_close_pipe(), since usbd_close_pipe() already takes care
about aborting non-empty pipes.

Nuke all occurrences of usbd_abort_pipe() if it gets called right
before usbd_close_pipe(), since usbd_close_pipe() already takes care
about aborting non-empty pipes.

As investigated by gerhard@ usbdi.c rev. 1.57 did add usbd_abort_pipe()
to usbd_close_pipe(), but the drivers didn't get cleaned up afterwards.

Change users of IFQ_SET_MAXLEN() and IFQ_IS_EMPTY() to use the "new" API.

Do not call encap routines with the IFQ mutex held, as they might
sleep in the stop routine in case of errors.

Ensure Rx/Tx resources are freed during interface stop.

In mue_iff() move the initialization of the hash table up so that is done
unconditionally, like it's done on other devices, so that we don't end up in
the situation of the card being put in promiscuo

In mue_iff() move the initialization of the hash table up so that is done
unconditionally, like it's done on other devices, so that we don't end up in
the situation of the card being put in promiscuous mode or if
ac->ac_multirangecnt > 0 and then we would write into the table while being
uninitialized a little bit later.

- use memset() for for clearing hashtbl
- the switch case for IFM_100_TX was the same code as for IFM_1000_T so it
can be rolled into one.

Add mue(4), a driver for Microchip LAN75xx/LAN78xx 10/100/1000 USB Ethernet
adapters.
