2010-06-25loopback: use u64_stats_sync infrastructureEric Dumazet1-46/+16
Commit 6b10de38f0ef (loopback: Implement 64bit stats on 32bit arches) introduced 64bit stats in loopback driver, using a private seqcount and private helpers. David suggested to introduce a generic infrastructure, added in (net: Introduce u64_stats_sync infrastructure) This patch reimplements loopback 64bit stats using the u64_stats_sync infrastructure.

Commit 59d4289b83b11379d867e2f7146904b19cc96404 converted fec to dev_pm_ops but didn't update the suspend/resume functions thus leading to the following warning : "initialization from incompatible pointer type" when CONFIG_PM is set. This patch also fixe a few indentation and style around CONFIG_PM area.

2010-06-25sfc: Fix reading of inserted hashBen Hutchings2-8/+6
The hash appears immediately before the packet data, not at the beginning of the buffer. This means we can easily use negative offsets from the start of packet data, so adjust the data and length at the top of __efx_rx_packet() instead of wherever we consume the hash.

2010-06-25enic: Use a lighter reset operation for enic devicesVasanthy Kolluri4-8/+55
The port profile information for a dynamic enic device is set by the upper layers, that are oblivious to the device reset operation. We do not want a reset operation erase the network state of a dynamic enic device as there is no way to set up the port profile information again. Hence a lighter reset operation called hang reset is used. Hang reset, unlike soft reset does not reset the network state and resets the host side state only.

sky2_phy_reinit is called by the ethtool helpers sky2_set_settings, sky2_nway_reset and sky2_set_pauseparam when netif_running. However, at the end of sky2_phy_init GM_GP_CTRL has GM_GPCR_RX_ENA and GM_GPCR_TX_ENA cleared.
