[net-next PATCH 01/26] igb: optomize/refactor receive path

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

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.

[net-next PATCH 02/26] igb: move setting of buffsz out of repeated path in alloc_rx_buffers

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

buffsz is being repeatedly set when allocaing buffers.  Since this value
should only need to be set once in the function I am moving it out of the
looped portion of the path.

[net-next PATCH 03/26] igb: move initialization of number of queues into set_interrupt_capability

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

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.

[net-next PATCH 04/26] igb: remove check for needing an io port

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

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.

[net-next PATCH 07/26] igb: read address from RAH/RAL instead of from EEPROM

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

Instead of pulling the mac address from EEPROM it is easier to pull it from
the RAL/RAH registers and then just copy it into the address structures.

[net-next PATCH 08/26] igb: rename phy ops

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

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.

[net-next PATCH 09/26] igb: rename nvm ops

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

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.

[net-next PATCH 11/26] igb: update feature flags supported in ethtool

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

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.

[net-next PATCH 12/26] igb: update testing done by ethtool

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

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.

[net-next PATCH 15/26] igb: remove redundant timer updates and cleanup watchdog_task

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

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.

[net-next PATCH 16/26] igb: rename igb_update_mc_addr_list_82575 to not include the 82575

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

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.

[net-next PATCH 17/26] igb: remove unnecessary adapter->hw calls when just hw-> will do.

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

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.

[net-next PATCH 18/26] igb: don't read eicr when responding to legacy interrupts

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

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.

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.

[Jeff Kirsher]

From: Alexander Duyck <alexander.h.duyck@intel.com>

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.

This patch addresses two minor items I found while cleaning up the igb

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.
