2011-01-10	IPoIB: Remove LRO support	Or Gerlitz	1	-51/+0
	As a first step in moving from LRO to GRO, revert commit af40da894e9 ("IPoIB: add LRO support"). Also eliminate the ethtool set_flags callback which isn't needed anymore. Finally, we need to include <linux/sched.h> directly to get the declaration of restart_syscall() (which used to be included implicitly through <linux/inet_lro.h>).

2010-07-04	IB/{nes, ipoib}: Pass supported flags to ethtool_op_set_flags()	Ben Hutchings	1	-1/+6
	Following commit 1437ce3983bcbc0447a0dedcd644c14fe833d266 "ethtool: Change ethtool_op_set_flags to validate flags", ethtool_op_set_flags takes a third parameter and cannot be used directly as an implementation of ethtool_ops::set_flags. Changes nes and ipoib driver to pass in the appropriate value. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Acked-by: Roland Dreier <rolandd@cisco.com> Signed-off-by: David S.

2010-04-21	IPoIB: Allow disabling/enabling TSO on the fly through ethtool	Or Gerlitz	1	-0/+20

2010-02-11	IPoIB: Remove TX moderation settings from ethtool support	Or Gerlitz	1	-8/+2
	As of commit f56bcd8 ("IPoIB: Use separate CQ for UD send completions"), there are no TX interrupts. Change the ethtool code not to report TX moderation settings, so users will not be misled to think they can control TX interrupt moderation.

2008-10-22	IPoIB: Clean up ethtool support	Or Gerlitz	1	-1/+8
	Add a get_rx_csum method. Remove the driver's own get_tso method, as the ethtool kernel code uses the default one if nothing is provided. Signed-off-by: Or Gerlitz <ogerlitz@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-07-14	IPoIB: add LRO support	Vladimir Sokolovsky	1	-0/+46
	Add "ipoib_use_lro" module parameter to enable LRO and an "ipoib_lro_max_aggr" module parameter to set the max number of packets to be aggregated. Make LRO controllable and LRO statistics accessible through ethtool.

2008-04-29	IPoIB: Use separate CQ for UD send completions	Eli Cohen	1	-1/+1
	Use a dedicated CQ for UD send completions. Also, do not arm the UD send CQ, which reduces the number of interrupts generated. This patch farther reduces overhead by not calling poll CQ for every posted send WR -- it does polls only when there 16 or more outstanding work requests.

2008-04-16	IPoIB: Support modifying IPoIB CQ event moderation	Eli Cohen	1	-0/+46
	This can be used to tune at run time the parameters controlling the event (interrupt) generation rate and thus reduce the overhead incurred by handling interrupts resulting in better throughput. Since IPoIB uses a single CQ for both RX and TX, RX is chosen to dictate configuration for both RX and TX.

2008-04-16	IPoIB: Add basic ethtool support	Eli Cohen	1	-0/+53
	Just add the infrastructure so we can add functionality later. Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
