sfc: Fix reporting of IPv4 full filters through ethtool

2012-10-02T17:38:55Z

[ Upstream commit ac70b2e9a13423b5efa0178e081936ce6979aea5 ] ETHTOOL_GRXCLSRULE returns filters for a TCP/IPv4 or UDP/IPv4 4-tuple with source and destination swapped. Signed-off-by: Ben Hutchings Signed-off-by: Greg Kroah-Hartman

sfc: Fix maximum number of TSO segments and minimum TX queue size

2012-10-02T17:38:39Z

[ Upstream commit 7e6d06f0de3f74ca929441add094518ae332257c ] Currently an skb requiring TSO may not fit within a minimum-size TX queue. The TX queue selected for the skb may stall and trigger the TX watchdog repeatedly (since the problem skb will be retried after the TX reset). This issue is designated as CVE-2012-3412. Set the maximum number of TSO segments for our devices to 100. This should make no difference to behaviour unless the actual MSS is less than about 700. Increase the minimum TX queue size accordingly to allow for 2 worst-case skbs, so that there will definitely be space to add an skb after we wake a queue. To avoid invalidating existing configurations, change efx_ethtool_set_ringparam() to fix up values that are too small rather than returning -EINVAL.

drivers/net: Convert compare_ether_addr to ether_addr_equal

2012-05-11T03:33:01Z

Use the new bool function ether_addr_equal to add some clarity and reduce the likelihood for misuse of compare_ether_addr for sorting. Done via cocci script: $ cat compare_ether_addr.cocci @@ expression a,b; @@ - !compare_ether_addr(a, b) + ether_addr_equal(a, b) @@ expression a,b; @@ - compare_ether_addr(a, b) + !ether_addr_equal(a, b) @@ expression a,b; @@ - !ether_addr_equal(a, b) == 0 + ether_addr_equal(a, b) @@ expression a,b; @@ - !ether_addr_equal(a, b) != 0 + !ether_addr_equal(a, b) @@ expression a,b; @@ - ether_addr_equal(a, b) == 0 + !ether_addr_equal(a, b) @@ expression a,b; @@ - ether_addr_equal(a, b) != 0 + ether_addr_equal(a, b) @@ expression a,b; @@ - !!ether_addr_equal(a, b) + ether_addr_equal(a, b) Signed-off-by: Joe Perches Signed-off-by: David S.

sfc: Added support for new ethtool APIs for obtaining module eeprom

2012-05-10T02:10:46Z

Currently allows for SFP+ eeprom to be returned using the ethtool API. This can be extended in future to handle different eeprom formats and sizes Signed-off-by: Stuart Hodgson [bwh: Drop redundant validation, comment, whitespace] Signed-off-by: Ben Hutchings

sfc: By default refill RX rings as soon as space for a batch

2012-05-10T01:22:17Z

Previously we refilled with much larger batches, which caused large latency spikes. We now have many more much much smaller spikes! Signed-off-by: Ben Hutchings

sfc: Fill RX rings completely full, rather than to 95% full

2012-05-10T01:22:17Z

There was no runtime control of the fast_fill_limit in any case, so purged that field. Signed-off-by: Ben Hutchings

sfc: Fix missing cleanup in failure path of efx_pci_probe()

2012-05-10T01:22:16Z

We need to clear the private data pointer in the PCI device. Also reorder cleanup in efx_pci_remove() for symmetry. Signed-off-by: Ben Hutchings

sfc: Do not attempt to flush queues if DMA is disabled

2012-05-10T01:22:08Z

efx_nic_fatal_interrupt() disables DMA before scheduling a reset. After this, we need not and *cannot* flush queues. Signed-off-by: Ben Hutchings
