IPoIB: Remove LRO support
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>).

IB/{nes, ipoib}: Pass supported flags to ethtool_op_set_flags()
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.

IPoIB: Remove TX moderation settings from ethtool support
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. Pointed out by Alex
Vainman <alexv@voltaire.com>

IPoIB: Clean up ethtool support
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.

IPoIB: add LRO support
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.

IPoIB: Use separate CQ for UD send completions
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.

IPoIB: Support modifying IPoIB CQ event moderation
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.
