This patch removes random mac assignment on vf's. The vf's will start with a zero mac and with upcoming support in fw/driver, a vf mac can be set via the pf. vf's also support ndo_set_mac_address. This decision was made based on the fact that a random mac on a vf is not really needed. And this will reduce some of the problems with the vf's getting a new mac on every driver load/unload (one of them being udev renaming the device on ever load/unload and reboot).

v2: Fixed up the bad typecasting pointed out by David... In the current design 8 TXQs are serviced by 1 EQ, while each RSS queue is serviced by a separate EQ. This is being changed as follows: - Upto 8 EQs will be used (based on the availabilty of msix vectors). Each EQ will handle 1 RSS and 1 TX ring. The default non-RSS RX queue and MCC queue are handled by the last EQ. - On cards which provide support, upto 8 RSS rings will be used, instead of the current limit of 4. The new design allows spreading the TX multi-queue completion processing across multiple CPUs unlike the previous design. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

Renamed dev_hw_addr_random to eth_hw_addr_random() to reflect that this function only assign a random ethernet address (MAC). Removed the second parameter (u8 *hwaddr), it's redundant since the also given net_device already contains net_device->dev_addr. Set it directly. Adapt igbvf and ixgbevf to the changed function. Small fix for ixgbevf_probe(): if ixgbevf_sw_init() fails (which means the device got no dev_addr) handle the error and jump to err_sw_init as already done by igbvf in similar case.

If eth_mac_addr() get called, usually if SIOCSIFHWADDR was used to change the MAC of a ethernet device, reset the addr_assign_type to NET_ADDR_PERM if the state was NET_ADDR_RANDOM before.

Currently, it is not easily possible to get TOS/DSCP value of packets from an incoming TCP stream. The mechanism is there, IP_PKTOPTIONS getsockopt with IP_RECVTOS set, the same way as incoming TTL can be queried. This is not actually implemented for TOS, though. This patch adds this functionality, both for IPv4 (IP_PKTOPTIONS) and IPv6 (IPV6_2292PKTOPTIONS). For IPv4, like in the IP_RECVTTL case, the value of the TOS field is stored from the other party's ACK. This is needed for proxies which require DSCP transparency. One such example is at http://zph.bratcheda.org/. Signed-off-by: Jiri Benc <jbenc@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This change combines a number of post-DMA Rx packet processing functions into a single function. The advantage of this is that it combines most of the Rx descriptor processing into one spot so it should all be warm in the cache.

It doesn't make much sense to differentiate between advanced and legacy descriptors when the only descriptors that ixgbe uses are advanced descriptors.

This change makes it so that we always clear the status/error bits in the Rx descriptor in the allocation path instead of the cleanup path. The advantage to this is that we spend less time modifying data. As such we can modify the data once and then let it go cold in the cache instead of writing it, reading it, and then writing it again.

This patch is meant to address the fact that RSC has not been setting the gso_size value on the skb. As a result performance on lossy TCP connections was negatively impacted.

This change addresses several issue. First I had left the use of the next and prev skb pointers floating around in the code and they were overdue to be pulled since I had rewritten the RSC code in the out-of-tree driver some time ago to address issues brought up by David Miller in regards to this. I am also now defaulting to always leaving the first buffer unmapped on any packet and then unmapping it after we read the EOP descriptor. This allows a simplification of the path with less branching. Instead of counting packets received the code was changed some time ago to track the number of buffers received. This leads to inaccurate counting when you compare numbers of packets received by the hardware versus what is tracked by the software. To correct this I am revising things so that the append_cnt value for RSC accurately tracks the number of frames received.

Quoth David: 1) GRO MAC header comparisons were ethernet specific, breaking other link types. This required a multi-faceted fix to cure the originally noted case (Infiniband), because IPoIB was lying about it's actual hard header length. Thanks to Eric Dumazet, Roland Dreier, and others. 2) Fix build failure when INET_UDP_DIAG is built in and ipv6 is modular. From Anisse Astier. 3) Off by ones and other bug fixes in netprio_cgroup from Neil Horman. 4) ipv4 TCP reset generation needs to respect any network interface binding from the socket, otherwise route lookups might give a different result than all the other segments received. From Shawn Lu. 5) Fix unintended regression in ipv4 proxy ARP responses, from Thomas Graf. 6) Fix SKB under-allocation bug in sh_eth, from Yoshihiro Shimoda. 7) Revert skge PCI mapping changes that are causing crashes for some folks, from Stephen Hemminger. 8) IPV4 route lookups fill in the wildcarded fields of the given flow lookup key passed in, which is fine most of the time as this is exactly what the caller's want. However there are a few cases that want to retain the original flow key values afterwards, so handle those cases properly. Fix from Julian Anastasov. 9) IGB/IXGBE VF lookup bug fixes from Greg Rose. 10) Properly null terminate filename passed to ethtool flash device method, from Ben Hutchings. 11) S3 resume fix in via-velocity from David Lv. 12) Fix double SKB free during xmit failure in CAIF, from Dmitry Tarnyagin. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (72 commits) net: Don't proxy arp respond if iif == rt->dst.dev if private VLAN is disabled ipv4: Fix wrong order of ip_rt_get_source() and update iph->daddr. netprio_cgroup: fix wrong memory access when NETPRIO_CGROUP=m netprio_cgroup: don't allocate prio table when a device is registered netprio_cgroup: fix an off-by-one bug bna: fix error handling of bnad_get_flash_partition_by_offset() isdn: type bug in isdn_net_header() net: Make qdisc_skb_cb upper size bound explicit. ixgbe: ethtool: stats user buffer overrun ixgbe: dcb: up2tc mapping lost on disable/enable CEE DCB state ixgbe: do not update real num queues when netdev is going away ixgbe: Fix broken dependency on MAX_SKB_FRAGS being related to page size ixgbe: Fix case of Tx Hang in PF with 32 VFs ixgbe: fix vf lookup igb: fix vf lookup e1000: add dropped DMA receive enable back in for WoL gro: more generic L2 header check IPoIB: Stop lying about hard_header_len and use skb->cb to stash LL addresses zd1211rw: firmware needs duration_id set to zero for non-pspoll frames net: enable TC35815 for MIPS again ...

Commit 653241 (net: RFC3069, private VLAN proxy arp support) changed the behavior of arp proxy to send arp replies back out on the interface the request came in even if the private VLAN feature is disabled. Previously we checked rt->dst.dev != skb->dev for in scenarios, when proxy arp is enabled on for the netdevice and also when individual proxy neighbour entries have been added. This patch adds the check back for the pneigh_lookup() scenario. Signed-off-by: Thomas Graf <tgraf@suug.ch> Acked-by: Jesper Dangaard Brouer <hawk@comx.dk> Signed-off-by: David S.

So we delay the allocation till the priority is set through cgroup, and this makes skb_update_priority() faster when it's not set.
