This patch eliminates an unnecessary poll-related routine by merging it into TIPC's main polling routine, and updates the comments associated with this code. Signed-off-by:

Currently each vlan_groupd contains 8 pointers on arrays with 512 pointers on struct net_device each :) Such a construction "in many cases ... wastes memory". My proposal is to allow for some of these arrays pointers be NULL, meaning that there are no devices in it. When a new device is added to the vlan_group, the appropriate array is allocated. The check in vlan_group_get_device's is safe, since the pointer vg->vlan_devices_arrays[x] can only switch from NULL to not-NULL. The vlan_group_prealloc_vid() is guarded with rtnl lock and is also safe. I've checked (I hope that) all the places, that use these arrays and found, that the register_vlan_dev is the only place, that can put a vlan device on an empty vlan_group. Rough calculations shows, that after the patch a setup with a single vlan dev (or up to 512 vlans with sequential vids) will occupy approximately 8 times less memory. The question I have is - does this patch makes sense, or a totally new structures are required to store the vlan_devs? Signed-off-by:

This mostly re-uses the net, used in icmp netnsization patches from Denis. After this ICMP sysctls are completely virtualized. Signed-off-by:

Add some flesh to ipv4_sysctl_init_net and ipv4_sysctl_exit_net, i.e. copy the table, alter .data pointers and register it per-net. Other ipv4_table's sysctls are now global, but this is going to change once sysctl permissions patches migrate from -mm tree to mainline in 2.6.26 merge window :) Signed-off-by:

Recent commits from YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> have been introduced a several compilation warnings 'assignment discards qualifiers from pointer target type' due to extra const modifier in the inline call parameters of {dev|sock|twsk}_net_set. Drop it. Signed-off-by:Denis V. Lunev <den@openvz.org> Signed-off-by:

- Fix Rx/Tx HW interrupt coalescing counter reset logic. Disabling is required before resetting the counter. - Update the Default both Rx and Tx coalescing timer threshold. Formerly 4 is set which is equal to 1.5 frame at the line rate of 1GbE interface, and it doesn't match to the coalescing frame count which is set to 16. Threashold 21 is matched to frame count 16.

If the LAST bit is not set in the RxBD, it's possible we're processing an incomplete frame, which is bad. While we're at it, add a constant for the error bitmask, so the whole if-clause fits on one line, and is more legible. Signed-off-by:

In gfar_change_mtu(), the frame size needs to be increased to account for the extra 4 bytes VLAN adds to the ethernet header. However, it was being increased by the length of the whole header (18 bytes), which is wrong. Signed-off-by:

This patch adds support for BCM5481 PHY. Unfortunately it's hard to get specifications for this PHY, so its special register 0x18 isn't annotated properly (but we know it's used to set up the delays). I've kept the magic numbers, so we'll not forget to fix it at the first opportunity, and will name that register and its bits correctly. p.s. also fixed the line with broken indention, introduced by commit 03157ac3 PHYLIB: Add BCM5482 PHY support Signed-off-by:

Robert P.J. Day proposed to use the macro FIELD_SIZEOF in replace of code that matches its definition.

isa_bus_to_virt() is the wrong thing to do here; it happens to work on i386, but only by accident. What we want is normal ioremap/readb/etc. set - it's all in iomem. Signed-off-by:

Driver is still broken, though; partially from Alan's checkpatch-induced fun, partially from layers of ancient mess ;-) By the end of the series... hell, might be even worth trying to stick such card into old alpha or ppc with an ISA slot and see if it work - would be for the first time ever in case of alpha and for the first time since at least 2.5.3 in case of ppc...

ixgb can remove irq_sem by auditing all the call sites to make sure that each of them makes sure the adapter is in the correct state before re-enabling interrupts. after doing this to all of our other drivers it is becoming easier. Signed-off-by:

irq_sem was just a hack to prevent interrupts from being enabled unexpectedly in deep call paths. Simply finding those call paths and fixing them by hand results in a driver that behaves as we expect and doesn't need the atomic at all. Signed-off-by:

In order to remove the irq_sem code we need to implement strict adapter state checking to prevent accidental double up or downs or resets. This code is largely copied from e1000/e1000e. Signed-off-by:
