* igb: Remove artificial restriction on RQDPC stat readingAlexander Duyck2013-02-171-3/+5
| | | | | | | | | | | | | | | | commit ae1c07a6b7ced6c0c94c99e3b53f4e7856fa8bff upstream. For some reason the reading of the RQDPC register was being artificially limited to 4K. Instead of limiting the value we should read the value and add the full amount. Otherwise this can lead to a misleading number of dropped packets when the actual value is in fact much higher.

* igb: Fix lack of flush after register write and before delayCarolyn Wyborny2011-08-291-0/+1
| | | | | | | | | | | | | | | | commit 064b43304ed8ede8e13ff7b4338d09fd37bcffb1 upstream. Register writes followed by a delay are required to have a flush before the delay in order to commit the values to the register. Without the flush, the code following the delay may not function correctly.

* igb: fix i350 SR-IOV failtureWilliams, Mitch A2011-06-071-0/+3
| | | | | | | | | | | | | | | | | When SR-IOV is enabled, i350 devices fail to pass traffic. This is due to the driver attempting to enable RSS on the PF device, which is not supported by the i350. When max_vfs is specified on an i350 adapter, set the number of RSS queues to 1. This issue affects 2.6.39 as well.

* ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny2011-04-291-4/+4
| | | | | | | | | | | | | | | | | | | | This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation.

* igb: add support for VF Transmit rate limit using iproute2Lior Levy2011-02-244-2/+99
| | | | | | | | | | | | | | | | | | | | | | | Implemented igb_ndo_set_vf_bw function which is being used by iproute2 tool. In addition, updated igb_ndo_get_vf_config function to show the actual rate limit to the user. The rate limitation can be configured only when the link is up. The rate limit value can be ranged between 0 and actual link speed measured in Mbps. A value of '0' disables the rate limit for this specific VF. iproute2 usage will be 'ip link set ethX vf Y rate Z'. After the command is made, the rate will be changed instantly. To view the current rate limit, use 'ip link show ethX'. The rates will be zeroed only upon driver reload or a link speed change. This feature is being supported only by 82576 device.

* | | igb: clear VF_PROMISC bits instead of setting all other bitsAlexander Duyck2010-09-221-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change corrects an issue in which we were setting all flag bits except for promisc instead of clearing the promisc bits due to the incorrect use of an |= instead of an &=.

* | | drivers/net: avoid some skb->ip_summed initializationsEric Dumazet2010-09-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fresh skbs have ip_summed set to CHECKSUM_NONE (0) We can avoid setting again skb->ip_summed to CHECKSUM_NONE in drivers. Introduce skb_checksum_none_assert() helper so that we keep this assertion documented in driver sources. Change most occurrences of : skb->ip_summed = CHECKSUM_NONE; by : skb_checksum_none_assert(skb); Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
