* netprio_cgroup: Fix build breakNeil Horman2011-11-231-13/+5
| | | | | | | | | | I broke the build with the addition of netprio_cgroups if CONFIG_CGROUPS=n. This patch corrects it by moving the offending struct into an ifdef CONFIG_CGROUPS block. Also clean up a few needless defines and inline functions that don't get called if CONFIG_CGROUPS isn't defined while Im at it.

* net: remove netdev_alloc_page and use __GFP_COLDEric Dumazet2011-11-228-52/+18
| | | | | | | | | | | | | | | | Given we dont use anymore the struct net_device *dev argument, and this interface brings litle benefit, remove netdev_{alloc|free}_page(), to debloat include/linux/skbuff.h a bit. (Some drivers used a mix of these interfaces and alloc_pages()) When allocating a page given to device for DMA transfer (device to memory), it makes sense to use a cold one (__GFP_COLD) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Jeff Kirsher <jeffrey.t.kirsher@intel.com> CC: Dimitris Michailidis <dm@chelsio.com> Signed-off-by: David S.

* net: add network priority cgroup infrastructure (v4)Neil Horman2011-11-2210-1/+469
| | | | | | | | | | | | | | | | | | | | | | | | | This patch adds in the infrastructure code to create the network priority cgroup. The cgroup, in addition to the standard processes file creates two control files: 1) prioidx - This is a read-only file that exports the index of this cgroup. This is a value that is both arbitrary and unique to a cgroup in this subsystem, and is used to index the per-device priority map 2) priomap - This is a writeable file. On read it reports a table of 2-tuples <name:priority> where name is the name of a network interface and priority is indicates the priority assigned to frames egresessing on the named interface and originating from a pid in this cgroup This cgroup allows for skb priority to be set prior to a root qdisc getting selected. This is benenficial for DCB enabled systems, in that it allows for any application to use dcb configured priorities so without application modification Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: John Fastabend <john.r.fastabend@intel.com> CC: Robert Love <robert.w.love@intel.com> CC: "David S.

| | | | | | | | | | | | | | | | | | | | | Commit 28011cf19b (net: Add ethtool to mii advertisment conversion helpers) added a helper function ethtool_adv_to_mii_100bt() and tg3_copper_is_advertising_all(), tg3_phy_autoneg_cfg() were modified to use this. Before that commit, ethtool to mii advertisement conversion was done wrt speed, but now pause operation is also taken account. So, in tg3_copper_is_advertising_all(), below condition becomes true and this makes link up fails. if ((adv_reg & ADVERTISE_ALL) != all_mask) return 0; To fix this add ADVERTISE_ALL bit and operation to cap speed, and change default advertisement not including ADVERTISED_Pause.

* netfilter: use jump_label for nf_hooksEric Dumazet2011-11-212-6/+33
| | | | | | | | | | | | | | | | | | On configs where CONFIG_JUMP_LABEL=y, we can replace in fast path a load/compare/conditional jump by a single jump with no dcache reference. Jump target is modified as soon as nf_hooks[pf][hook] switches from empty state to non empty states. jump_label state is kept outside of nf_hooks array so has no cost on cpu caches. This patch removes the test on CONFIG_NETFILTER_DEBUG : No need to call nf_hook_slow() at all if nf_hooks[pf][hook] is empty, this didnt give useful information, but slowed down things a lot.

* tg3: switch to build_skb() infrastructureEric Dumazet2011-11-212-55/+66
| | | | | | | | | | | | | | | | This is very similar to bnx2x conversion, but simpler since no special alignement is required, so goal was not to reduce skb truesize. Using build_skb() reduces cache line misses in the driver, since we use cache hot skb instead of cold ones. Number of in-flight sk_buff structures is lower, they are more likely recycled in SLUB caches while still hot.

It assumed ipv4_dst_check() would be called because all possible routes were attached to the inetpeer we modify in ip_rt_redirect(), but thats not true. commit 7cc9150ebe (route: fix ICMP redirect validation) tried to fix this but solution was not complete. (It fixed only one route) So we must lookup existing routes (including different TOS values) and call check_peer_redir() on them.

| | * | stmmac: parameters auto-tuning through HW cap regGiuseppe CAVALLARO2011-11-173-29/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New GMAC devices (newer than the databook 3.50a) have the HW capability register that provides which features are actually supported by the hardware. On old devices many information have to be passed through the platform, for example: enhanced descriptor structure, TX COE etc. These are mandatory to properly configure the driver. This remains still valid because the driver has to support old Synopsys devices but now it's also able to override them using the values from the HW capability register if supported.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch uses an mdelay to manage the timeout on sw reset to be independant of cpu_clk.

| | * | sky2: reduce default Tx ring sizestephen hemminger2011-11-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default Tx ring size for the sky2 driver is quite large and could cause excess buffer bloat for many users. The minimum ring size possible and still allow handling the worst case packet on 64bit platforms is 38 which gets rounded up to a power of 2. But most packets only require a couple of ring elements.

When setting registers, a read is necessary to force the writes to complete. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
