This patch optimises the Ethernet header comparison to use 2-byte and 4-byte xors instead of memcmp. In order to facilitate this, the actual comparison is now carried out by the callers of the shared dev_gro_receive function. This has a significant impact when receiving 1500B packets through 10GbE.

This patch prepares for the move of the same_flow checks out of dev_gro_receive. As such we need to remember the number of held packets since doing a loop just to count them every time is silly. Signed-off-by:

Several devices need to insert some "pre headers" in front of the main packet data when they transmit a packet. Currently we allocate only 16 bytes of pad room and this ends up not being enough for some types of hardware (NIU, usb-net, s390 qeth, etc.) So increase this to 32. Note that drivers still need to check in their transmit routine whether enough headroom exists, and if not use skb_realloc_headroom(). Tunneling, IPSEC, and other encapsulation methods can cause the padding area to be used up. Signed-off-by:

This patch addresses two minor items I found while cleaning up the igb driver for our sourceforge version. The first clears the context index if we don't flag that we need it. The second item is that eims_other should be used instead of bit defines when setting all of the EICS bits prior to reset. Signed-off-by:

It was seen with repeated interface up/down testing that there was a large stray between the stats reported by the queues and the stats reported by the HW. It was found to be an issue in that hw stats were being reset without first being recorded. This change records the stats before wiping them from the system via the reset. Signed-off-by:

Remove the setting of ring->count variables from igb_probe as they are duplicating the same configuration that is done igb_alloc_queues. Remove the err_hw_init tag as it can be replaced by err_sw_init. Signed-off-by:

The disable_av variable is never used by the driver and provides no value as it is likely a leftover debugging variable. I have removed it and replaced the one spot that checked for it with a check for a valid address. Signed-off-by:

As additional hardware is added to the igb driver it is easier to support the expansion via switch statements instead of using nested ifs. For this reason I am changing this to a switch statement. Signed-off-by:

Move igb_get_hw_control up so that it is called just after the reset in igb_resume. This notifies the HW sooner that the driver is reassuming control of the device. Signed-off-by:

The interrupt handler was reading eicr and then doing nothing with the result. I have removed the variable and the register read since they provide no value to the legacy interrupt handler. Signed-off-by:

There were several spots in the code making calls to adapter->hw when they could have just been accessing hw-> directly. I cleaned up the spots where this was visibly apparent. Signed-off-by:

There isn't much point in having the _82575 hanging off the end of this function since there aren't any other version of this function running around within this driver. This also allows for a bit of whitespace cleanup due to a shorter function name. Signed-off-by:

The igb watchdog task is modifying the watchdog timer twice duing a single run. It only needs to be called once to reschedule itself for 2 seconds from the last time it ran. In addition I removed the allocation of the mac_info structure since it is only called twice and is easier to access via the e1000_hw struct. Signed-off-by:

Most of the code for the testing has pretty much become stale at this point and is need of update. This update just streamlines most of the code, widens the range of interrupt testing. Signed-off-by:

This driver is currently using HW_CSUM which is not correct. Update this to use the IP_CSUM and IPV6_CSUM flags. In addition consolidate the TSO flag setting. Signed-off-by:

All of the nvm ops have the tag _nvm added to the end which is redundant since all of the calls to the ops have to go through the nvm ops struct anyway. Signed-off-by:

This patch renames write_phy_reg to write_reg and read_phy_reg to read_reg. It seems redundant to call out phy in an operation that is part of the phy_ops struct. Signed-off-by:

Since igb supports only pci-e nics and there is no plan to support any legacy pci parts in the driver there isn't really much need for checking to see if an io port is needed. In the unlikely event that we do begin supporting legacy pci parts then we can see about adding this code back to the driver. Signed-off-by:

This patch moves the initialization of the number of queues into set_interrupt_capability. This allows the number of queues to increase in the unlikely event that the system initially fails to allocate enough msi-x interrupts, does a suspend/resume, and then can allocate enough interrupts on resume.

While cleaning up the skb_over panic with small frames I found there was room for improvement in the ordering of operations within the rx receive flow. These changes will place the prefetch for the next descriptor to a point earlier in the rx path. Signed-off-by:

Unfortunately, the OF device tree nodes for SBUS and PCI hme devices have the same device node name on some systems. So if the name of the parent node isn't 'sbus', skip it. Based upon an excellent report and detective work by Meelis Roos and Eric Brower. Signed-off-by:

Now that our set_num_queues() routines for each feature are re-entrant, and can be called at any point, they shouldn't zero out the feature's indices or mask bits. Subsequent calls into those routines for those features can result in zero Rx and Tx queues being assigned, causing a panic later in driver reinitialization. Signed-off-by:
