sfc: Report software timestamping capabilities

2013-06-24T18:58:29+00:00

The kernel can generate software receive timestamps and we should
report those for all ports regardless of hardware capabilities.

sfc: Enable RX DMA scattering where possible

2013-03-07T20:22:12+00:00

Enable RX DMA scattering iff an RX buffer large enough for the current
MTU will not fit into a single page and the NIC supports DMA
scattering for kernel-mode RX queues.

On Falcon and Siena, the RX_USR_BUF_SIZE field is used as the DMA
limit for both all RX queues with scatter enabled.  Set it to 1824,
matching what Onload uses now.

Maintain a statistic for frames truncated due to lack of descriptors
(rx_nodesc_trunc).  This is distinct from rx_frm_trunc which may be
incremented when scattering is disabled and implies an over-length
frame.

Whenever an MTU change causes scattering to be turned on or off,
update filters that point to the PF queues, but leave others
unchanged, as VF drivers assume scattering is off.

Add n_frags parameters to various functions, and make them iterate:
- efx_rx_packet()
- efx_recycle_rx_buffers()
- efx_rx_mk_skb()
- efx_rx_deliver()

Make efx_handle_rx_event() responsible for updating
efx_rx_queue::removed_count.

Change the RX pipeline state to a starting ring index and number of
fragments, and make __efx_rx_packet() responsible for clearing it.

Based on earlier versions by David Riddoch and Jon Cooper.

sfc: Fix byte order warnings for ethtool RX filter interface

2012-12-01T00:26:06+00:00

sparse has got a bit more picky since I last ran it over this.  Add
forced casts for use of ~0 as a big-endian value.  Undo the pointless
optimisation of parameter validation with '|'; using '||' avoids these
warnings.

sfc: Remove EFX_FILTER_FLAG_RX_OVERRIDE_IP

2012-10-02T00:58:41+00:00

This filter flag cannot yet be set through the ethtool command and
will not be supported on future hardware.

sfc: Fix loopback self-test with separate_tx_channels=1

2012-10-02T00:58:41+00:00

The loopback self-test iterates over all the TX queues of channel 0,
which is not very interesting when that's an RX-only channel.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

2012-08-31T19:14:18+00:00

Merge the 'net' tree to get the recent set of netfilter bug fixes in
order to assist with some merge hassles Pablo is going to have to deal
with for upcoming changes.

sfc: Change state names to be clearer, and comment them

2012-08-24T19:10:18+00:00

STATE_INIT and STATE_FINI are equivalent and represent incompletely
initialised states; combine them as STATE_UNINIT.

Rename STATE_RUNNING to STATE_READY, to avoid confusion with
netif_running() and IFF_RUNNING.

The comments do not quite match current usage, but this will be
corrected in subsequent fixes.

sfc: Fix reporting of IPv4 full filters through ethtool

2012-08-24T03:17:21+00:00

ETHTOOL_GRXCLSRULE returns filters for a TCP/IPv4 or UDP/IPv4 4-tuple
with source and destination swapped.
