cpumask: use zalloc_cpumask_var() where possible

2009-09-24T00:04:24+00:00

Remove open-coded zalloc_cpumask_var() and zalloc_cpumask_var_node().

sfc: Improve reliability of RX queue flushing

2009-08-27T00:38:59+00:00

Reconfiguring the port requires us to flush all DMA queues.  In
repeated testing we have found that RX flushes would sometimes fail
because the RX DMA engine was not properly isolated from the MACs.

sfc: Fix ordering of device registration and initial netif_carrier_off()

2009-08-27T00:38:49+00:00

We must call netif_carrier_off() after the device is registered, not
before, to set the operational state and user-space IFF_RUNNING flag
correctly.

Since we don't want observers to see an intermediate state, open-code
register_netdev() and add efx_update_name() and netif_carrier_off()
into the locked region.

sfc: Remove lro module parameter

2009-05-19T23:19:08+00:00

GRO/LRO can be controlled through ethtool so this is unnecessary.

sfc: modify allocation error message

2009-05-17T18:59:50+00:00

Change error message when alloc_cpumask_var fails.

Repairs "cpumask: convert drivers/net/sfc".

sfc: Use generic MDIO functions and definitions

2009-04-30T00:32:30+00:00

Make use of the newly-added generic MDIO clause 45 support and remove
redundant definitions.

Add an 'efx_' prefix to the remaining driver-specific MDIO functions
and remove arguments which are redundant with efx->mdio.prtad.

sfc: Match calls to netif_napi_add() and netif_napi_del()

2009-04-15T02:47:46+00:00

sfc could call netif_napi_add() multiple times for the same
napi_struct, corrupting the list of napi_structs for the associated
device and leading to a busy-loop on device removal.  Move the call to
netif_napi_add() and add a call to netif_napi_del() in the obvious
places.

sfc: Call netif_napi_add() before registering our interrupt handler

2009-03-31T22:07:21+00:00

If we use a shared legacy IRQ then our interrupt handler may be called
as soon as it is registered even though IRQs are disabled on the NIC.
Now that the legacy interrupt handler also checks for event delivery,
it may decide to schedule polling in this case.  Ensure that the NAPI
context is valid but disabled at this point.

sfc: Implement adaptive IRQ moderation

2009-03-22T02:06:58+00:00

Calculate a score for each 1000 IRQs:
- TX completions are worth 1 point
- RX completions are worth 4 if merged using LRO or 2 otherwise

Reduce moderation if the score is less than 10000, down to a minimum
of 5 us.  Increase moderation if the score is more than 20000, up to
the specified maximum.
