2011-02-28sfc: Do not read STAT1.FAULT in efx_mdio_check_mmd()Ben Hutchings4-31/+8
This field does not exist in all MMDs we want to check, and all callers allow it to be set (fault_fatal = 0). Remove the loopback condition, as STAT2.DEVPRST should be valid regardless of any fault. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2011-02-28sfc: Read MC firmware version when requested through ethtoolBen Hutchings5-41/+9
We currently make no use of siena_nic_data::fw_{version,build} except to format the firmware version for ethtool_get_drvinfo(). Since we only read the version at start of day, this information is incorrect after an MC firmware update. Remove the cached version information and read it via MCDI whenever it is requested.

2011-02-27net: convert bonding to use rx_handlerJiri Pirko1-1/+73
This patch converts bonding to use rx_handler. Results in cleaner __netif_receive_skb() with much less exceptions needed. Also bond-specific work is moved into bond code. Did performance test using pktgen and counting incoming packets by iptables. No regression noted.

2011-02-24Revert "sch_netem: Remove classful functionality"stephen hemminger1-8/+79
Many users have wanted the old functionality that was lost to be able to use pfifo as inner qdisc for netem. The reason that netem could not be classful with the older API was because of the limitations of the old dequeue/requeue interface; now that qdisc API has a peek function, there is no longer a problem with using any inner qdisc's.

2011-02-24ipv4: Rearrange how ip_route_newports() gets port keys.David S. Miller3-12/+23
ip_route_newports() is the only place in the entire kernel that cares about the port members in the routing cache entry's lookup flow key. Therefore the only reason we store an entire flow inside of the struct rtentry is for this one special case. Rewrite ip_route_newports() such that: 1) The caller passes in the original port values, so we don't need to use the rth->fl.fl_ip_{s,d}port values to remember them. 2) The lookup flow is constructed by hand instead of being copied from the routing cache entry's flow.

2011-02-24igb: add support for VF Transmit rate limit using iproute2Lior Levy4-2/+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.
