# [PATCH] USB GeneLink/NDIS tweaks
#
# USB GeneLink/NDIS tweaks
#
# This patch, from Oliver, discards slightly less data in cases
# where memory is very tight. The GeneLink framing can batch
# several packets in one transmission, so it's always possible to
# at least report the last one, since it's already sitting in an SKB
# and we won't need a new one.
#
# Random note, this seems to be the same issue I saw
# mentioned somewhere else recently: MSFT host drivers
# with high latency for submitting bulk packets, so rather
# than just queuing them as they arrive, it turns out to be a
# win on the MSFT side to batch packets.
