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:

this patch is trivial but because I want to have everything be nice and tidy I'm updating it. 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:

ixgb needs to call flush scheduled work to flush any timers before unregistering the netdev. 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:

in order to prevent the case where poll_disable is waiting on our device to permanently, check the flag to make sure we're not down or closing down before re-enabling interrupts. Signed-off-by:

ixgb hardware (not ixgbe) has a problem where it might dma past the end of a buffer in certain cases. leave 8 bytes extra room. 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:

this patch has been made to many other drivers in kernel to fix the storage of 64 bit resources in 32 bit variables. 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:

- Enable msi-x link interrupts because the timer based scheduler was getting cancelled causing the link state to be lost with repetitive card up/downs when changing the mtu. - Unmask mac_rmac_link interrupts only for Xframe I and prevent a spurious link interrupt in Xframe II. - Stop the tx queue and indicate link down when card is down Signed-off-by:

Updates of the RBRDU have two different meanings depending on their context: 1. the receiving process has not started - the value which is written into the RBRDU register is supposed to be the free rx descriptors count (rounded to a multiple of 4) 2. the receiving process is running - the value increments the count above (sic) The update is currently issued deep inside the rx replenish chain (see velocity_give_many_rx_descs). Let's propagate enough information to the caller so that the rx replenish functions do not depend on hardware any more. It is needed to perform the Rx/Tx buffers housekeeping when MTU changes.

- PCI consistent areas need no memset - use dev_err instead of plain printk - avoid a few casts Signed-off-by:

Executive summary: the bounce buffers are in my way - they use something like a 64 * 1500 bytes area of PCI consistent area - they are not resized when the MTU changes - they are used - to hand-pad undersized packets. skb_pad anyone ? - to linearize fragmented skbs whose fragment count goes beyond the 7 fragments hardware limit in order to claim scatter-gather support Actually the SG code is commented out and I wonder if it could not be implemented (ab-)using the large send feature of the chipset since the latter should support some multi-descriptor packet transmitting.

Only plain netif_schedule() remains taking a net_device, mostly as a compatability item while we transition the rest of these interfaces. Everything else calls netif_schedule_queue() or __netif_schedule(), both of which take a netdev_queue pointer. Signed-off-by:
