sfc: Only cancel the PPS workqueue if it exists

2019-11-21T20:06:06+00:00

The workqueue only exists for the primary PF. For other functions
we hit a WARN_ON in kernel/workqueue.c.

sfc: falcon: don't score irq moderation points for GRO

2019-08-09T01:22:29+00:00

Same rationale as for sfc, except that this wasn't performance-tested.

sfc: don't score irq moderation points for GRO

2019-08-09T01:22:29+00:00

We already scored points when handling the RX event, no-one else does this,
 and looking at the history it appears this was originally meant to only
 score on merges, not on GRO_NORMAL.  Moreover, it gets in the way of
 changing GRO to not immediately pass GRO_NORMAL skbs to the stack.
Performance testing with four TCP streams received on a single CPU (where
 throughput was line rate of 9.4Gbps in all tests) showed a 13.7% reduction
 in RX CPU usage (n=6, p=0.03).

net: Use skb_frag_off accessors

2019-07-30T21:21:32+00:00

Use accessor functions for skb fragment's page_offset instead
of direct references, in preparation for bvec conversion.

net: sfc: falcon: convert to i2c_new_dummy_device

2019-07-25T18:19:19+00:00

Move from i2c_new_dummy() to i2c_new_dummy_device(). So, we now get an
ERRPTR which we use in error handling.

sfc: Remove 'PCIE error reporting unavailable'

2019-07-08T19:16:48+00:00

This is only at notice level but it was pointed out that no other driver
does this.
Also there is no action the user can take as it is really a property of
the server.
