        src/sys/dev/usb: if_axe.c if_axen.c if_cdce.c if_ure.c

Log Message:
in tx_prepare callback make sure to reject any mbuf that is larger
than can fit in the buffer.  done at the driver and not usbnet
layer because the driver knows how much beyond the mbuf data needs
to be sent (headers and trailers.)

axen(4) had a KASSERT() for this condition, but there's no
invariant here we can check so it's best as an error return.

XXX: only tested on these drivers, needs to be copied to udav, smsc
and urndis after testing as well as the not commited conversions.
