sfc: free multiple Rx buffers when required

2015-06-01T00:36:20Z

When Rx packet data must be dropped, all the buffers associated with that Rx packet must be freed. Extend and rename efx_free_rx_buffer() to efx_free_rx_buffers() and loop through all the fragments. By doing so this patch fixes a possible memory leak. Signed-off-by: Shradha Shah Signed-off-by: David S. Miller

sfc: Add support for busy polling

2014-07-23T02:55:20Z

This patch adds the sfc driver code for implementing busy polling. It adds ndo_busy_poll method and locking between it and napi poll. It also adds each napi to the napi_hash right after netif_napi_add(). Uses efx_start_eventq and efx_stop_eventq in the self tests. Signed-off-by: Shradha Shah Signed-off-by: David S. Miller

sfc: Add per-queue statistics in ethtool

2014-07-17T23:48:36Z

Implement per channel software TX and RX packet counters accessed as ethtool statistics. This allows confirmation with MAC statistics. Signed-off-by: Shradha Shah Signed-off-by: David S. Miller

sfc: add extra RX drop counters for nodesc_trunc and noskb_drop

2014-07-16T05:53:34Z

Added a counter rx_noskb_drop for failure to allocate an skb. Summed the per-channel rx_nodesc_trunc counters earlier so that they can be included in rx_dropped. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

net: sfc calls skb_set_hash

2013-12-18T20:00:53Z

Drivers should call skb_set_hash to set the hash and its type in an skbuff. Signed-off-by: Tom Herbert Signed-off-by: David S. Miller

sfc: Add RX packet timestamping for EF10

2013-12-12T22:07:13Z

The EF10 firmware can optionally insert RX timestamps in the packet prefix. These only include the clock minor value. We must also enable periodic time sync events on each event queue which provide the high bits of the clock value. [bwh: Combined and rebased several changes. Added the above description and some sanity checks for inline vs separate timestamps. Changed efx_rx_skb_attach_timestamp() to read the packet prefix from the skb head area.] Signed-off-by: Ben Hutchings

sfc: Copy RX prefix into skb head area in efx_rx_mk_skb()

2013-12-12T22:07:12Z

We can potentially pull the entire packet contents into the head area and then free the page it was in. In order to read an inline timestamp safely, we need to copy the prefix into the head area as well. Signed-off-by: Ben Hutchings

sfc: Make initial fill of RX descriptors synchronous

sfc: RX buffer allocation takes prefix size into account in IP header alignment

2013-12-06T22:27:52Z

rx_prefix_size is 4-bytes aligned on Falcon/Siena (16 bytes), but it is equal to 14 on EF10. So, it should be taken into account if arch requires IP header to be 4-bytes aligned (via NET_IP_ALIGN). Fixes: 8127d661e77f ('sfc: Add support for Solarflare SFC9100 family') Signed-off-by: Ben Hutchings

sfc: Support ARFS for IPv6 flows

2013-09-20T18:32:00Z

Extend efx_filter_rfs() to map TCP/IPv6 and UDP/IPv6 flows into efx_filter_spec. These are only supported on EF10; on Falcon and Siena they will be rejected by efx_farch_filter_from_gen_spec(). Signed-off-by: Ben Hutchings
