Revision 22e1170310ec6afa41e0dc7ac9dfac735d82dcab authored by Stephen Hemminger on 12 July 2006, 22:23:48 UTC, committed by Jeff Garzik on 12 July 2006, 22:39:22 UTC
When the driver handles multiple packets per NAPI poll, it is better to reload the receive ring, then tell the hardware. Otherwise, under packet storm with flow control, the driver/hardware will degrade down to one packet getting through per pause-exchange. Likewise on transmit, don't wakeup until a little more than minimum ring space is available. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

/* Please note that this file is also compiled into the xsim simulator.
Try to avoid breaking its double use (only works on a little-endian
32-bit machine such as the i386 anyway).
Use __KERNEL__ when you're about to use kernel functions,
(which you should not do here anyway, since this file is
used by glibc).
Use defined(__KERNEL__) || defined(__elinux__) when doing
things that only makes sense on an elinux system.
Use __CRIS__ when you're about to do (really) CRIS-specific code.
