i40e: Strip out debugfs hook for Flow Director filter programming

2016-09-25T05:41:47+00:00

This  interface was only ever meant for debug only. Since it is not
supposed to be here we are removing it.

i40e: fix "dump port" command when NPAR enabled

2016-09-23T05:33:38+00:00

When using the debugfs to issue the "dump port" command
with NPAR enabled, the firmware reports back with invalid argument.

The issue occurs because the pf->mac_seid was used to perform the query.
This is fine when NPAR is disabled because the switch ID == pf->mac_seid,
however this is not the case when NPAR is enabled.  This fix instead
goes through the VSI to determine the correct ID to use in either case.

i40e: refactor Rx filter handling

2016-07-22T07:07:04+00:00

Properly track filter adds and deletes so the driver doesn't lose filters
during resets and up/down cycles. Add a tracking mechanism so that the
driver knows when to enter and leave promiscuous mode.

Implement a simple state machine so the driver can track the status of
each filter throughout its lifecycle. Properly manage the overflow promiscuous
state for the each VSI, and provide a way for the driver to detect when to exit
overflow promiscuous mode.

Remove all possible default MAC filters that the firmware may have set up so
that the driver can manage these correctly, particularly when VLANs come into
play. Remove the LAA flag for filters; instead just send whatever we get through
set_mac to the firmware as the LAA for wakeup purposes.

Finally, add the state of each filter to debugfs output so we can see what's
going on inside the driver's pointy little head.

i40e/i40evf: Remove unused hardware receive descriptor code

2016-05-06T05:59:54+00:00

The hardware supports a 16 byte descriptor for receive, but the
driver was never using it in production.  There was no performance
benefit to the real driver of 16 byte descriptors, so drop a whole
lot of complexity while getting rid of the code.

Also since the previous patch made us use no-split mode all the
time, drop any support in the driver for any other value in dtype
and assume it is always zero (aka no-split).

Hooray for code removal!

i40e: Refactor receive routine

2016-05-06T04:53:16+00:00

This is part 1 of the Rx refactor series, just including
changes to i40e.

This refactor aligns the receive routine with the one in
ixgbe which was highly optimized.  This reduces the code
we have to maintain and allows for (hopefully) more readable
and maintainable RX hot path.

In order to do this:
- consolidate the receive path into a single function that doesn't
  use packet split but *does* use pages for Rx buffers.
- remove the old _1buf routine
- consolidate several routines into helper functions
- remove ethtool control over packet split

i40e/i40evf: Remove reference to ring->dtype

2016-05-06T01:59:23+00:00

As part of the rx-refactor, the dtype variable in the i40e_ring
struct is no longer used, so remove it.

i40e: remove redundant check on vsi->active_vlans

2016-04-06T01:52:14+00:00

active_vlans is an unsigned long array, hence a null check on this
array is superfluous and can be removed.

Detected with static analysis by smatch:

drivers/net/ethernet/intel/i40e/i40e_debugfs.c:386
  i40e_dbg_dump_vsi_seid() warn: this array is probably
  non-NULL. 'vsi->active_vlans'

i40e: queue-specific settings for interrupt moderation

2016-02-20T03:54:10+00:00

For i40e driver, each vector has its own ITR register. However, there
are no concept of queue-specific settings in the driver proper. Only
global variable is used to store ITR values. That will cause problems
especially when resetting the vector. The specific ITR values could be
lost.
This patch move rx_itr_setting and tx_itr_setting to i40e_ring to store
specific ITR register for each queue.
i40e_get_coalesce and i40e_set_coalesce are also modified accordingly to
support queue-specific settings. To make it compatible with old ethtool,
if user doesn't specify the queue number, i40e_get_coalesce will return
queue 0's value. While i40e_set_coalesce will apply value to all queues.

i40e: Removal of code which relies on BASE VEB SEID

2016-02-18T07:03:19+00:00

Fixed mapping of SEID is removed from specification. Hence
this patch removes code which was using hard coded base VEB SEID.

Changed FCoE code to use "hw->pf_id" to obtain correct "idx"
and verified.

Removed defines for BASE VSI/VEB SEID and BASE_PF_SEID since it
is not used anymore.
