This patch adds setting of the urb transfer flag URB_ZERO_PACKET before
submitting an urb for drivers that have requested it (by advertising flag
FLAG_SEND_ZLP).
The modification is in usbnet.c function usbnet_start_xmit().
This patch only adds the zero length flag.
A subsequent patch will address the buggy code we found when devices do not
advertise FLAG_SEND_ZLP in which case there is a possibility of transferring
packets with non-deterministic length.
This patch has been tested on kernel-2.6.34-rc3.
This patch has been checked against net-2.6 tree.
