Adds netif_napi_del function which is used to remove the napi struct from the netdev napi_list in cases where CONFIG_NETPOLL was enabled. The motivation for adding this is to handle the case in which the number of queues on a device changes due to a configuration change. Previously the napi structs for each queue would be left in the list until the netdev was freed. Signed-off-by:

Change igb from using a series of boolean operators to using a single flags value that contains a number of different bit flags for all the different features of the adapter. This patch also adds WOL support for quad port adapters. Signed-off-by:

We can remove a clunky workaround for not having the hardware strip the CRC. 82575 silicon as well as the older PCI Express e1000e hardware all work OK in this respect. Signed-off-by:

Add DCA support in the similar method that it was added to the ixgbe driver recently. DCA allows the network device to put data in the CPU cache and notify the chipset of that event. This reduces cache misses during receives. Signed-off-by:

This code adds multiple Tx queue infrastructure much like we previously did in ixgbe. The MSI-X vector mapping is the bulk of the change. IAM can now be safely enabled and we've verified that it does work correctly. We can also eliminate the tx ring lock. Signed-off-by:

rx cleanup should look more like our other drivers that have evolved to nicer performance levels over time. Changes consist of refilling tx buffers to hardware more often, some minor assignment cleanups. Signed-off-by:

a) kernel developers suggest LLTX is broken and unsafe to use, remove it. b) remember to pre-stop the queue if we won't have room c) removing lltx means we can remove our tx lock Signed-off-by:

some random coverage testing found that when changing mtu under heavy traffic load, NAPI would use the rx_buffer_len variable after it had been changed by change_mtu. Similar to e1000 bugs found long ago. Signed-off-by:

a user pointed out that setting variables out of order with respect to the checks we make for tx timeout handling could result in a race where ->dma was set but ->time_stamp was set to the old value. Signed-off-by:

there was one more bug hidden in the prefetch routines in ixgb hardware that force us to remove it completely. Writebacks were being done on descriptors with stale data due to internal hardware fifo corruption. Signed-off-by:

back when maybe stop tx was added to the ixgb driver some mistakes were made and the driver a) didn't remove the tx lock, which is now un-necessary b) didn't change the restart code to be compliant with maybe_stop Signed-off-by:
