Add appropriate include for prefetch users

2011-05-23T04:41:57+00:00

After discovering that wide use of prefetch on modern CPUs
could be a net loss instead of a win, net drivers which were
relying on the implicit inclusion of prefetch.h via the list
headers showed up in the resulting cleanup fallout.  Give
them an explicit include via the following $0.02 script.

 =========================================
 #!/bin/bash
 MANUAL=""
 for i in `git grep -l 'prefetch(.*)' .` ; do
 	grep -q '' $i
 	if [ $? = 0 ] ; then
 		continue
 	fi

 	(	echo '?^#include '
 		echo .
 		echo w
 		echo q
 	) | ed -s $i > /dev/null 2>&1
 	if [ $? != 0 ]; then
 		echo $i needs manual fixup
 		MANUAL="$i $MANUAL"
 	fi
 done
 echo ------------------- 8\<----------------------
 echo vi $MANUAL
 =========================================

sfc: Move test of rx_checksum_enabled from nic.c to rx.c

2011-04-01T21:20:06+00:00

This is preparation for using the generic netdev features interface,
and should have no effect in itself.

sfc: Reduce size of efx_rx_buffer further by removing data member

2011-02-28T23:57:23+00:00

Instead calculate the KVA of receive data. It's not like it's a hard sum.

[bwh: Fixed to work with GRO.]

sfc: convert references to LRO to GRO

2010-12-10T23:03:24+00:00

This driver now uses Generic Receive Offload, not the older LRO.
Change references to LRO in names and comments.

sfc: Make the dmaq size a run-time setting (rather than compile-time)

2010-09-10T19:27:33+00:00

- Allow the ring size to be specified in non
   power-of-two sizes (for instance to limit
   the amount of receive buffers).
 - Automatically size the event queue.

sfc: Refactor channel and queue lookup and iteration

2010-09-10T19:27:32+00:00

In preparation for changes to the way channels and queue structures
are allocated, revise the macros and functions used to look up and
iterator over them.

- Replace efx_for_each_tx_queue() with iteration over channels then TX
  queues
- Replace efx_for_each_rx_queue() with iteration over channels then RX
  queues (with one exception, shortly to be removed)
- Introduce efx_get_{channel,rx_queue,tx_queue}() functions to look up
  channels and queues by index
- Introduce efx_channel_get_{rx,tx}_queue() functions to look up a
  channel's queues
