there's several drivers that have use "tx_timeout" for the .. tx timeout function. All fine with that, they're static, however for doing stats on how often which driver hits the timeout it's a tad unfortunate. The patch below gives the ones I found in the kerneloops.org database unique names. Signed-off-by:

Since recent kernel (2.6.26 or 2.6.27) the PCI wakeup functions are influenced by generic device ability and configuration when enabling PCI-device triggered wake-up. This patch causes WoL setting to enable/disable device's wish to be permitted to wake-up the host when changing WoL options and also during device probing. Without this patch one has write 'enabled' to /sys/bus/pci/devices/0000:02:08.0/power/wakeup Signed-off-by:

The device's carrier status is controlled via the functions netif_carrier_on() and netif_carrier_off(). These set or clear a bit indicating the carrier (aka lower level link) is down, and if the state changed, they fire off a routing netlink event. Add a call to netif_carrier_off() before register_netdev() so that the newly created device will be set to carrier down. Then when the carrier comes up for the first time, a netlink event will be generated, as the carrier changed from down to up. Otherwise the initial carrier up will appear to be changing the status from up to up, and so no event is generated since that's not a change. Signed-off-by:

mv643xx_eth uses ip_hdr() (defined in linux/ip.h), but relied on another header file to include the needed header file indirectly. In latest net-next this indirect include chain is gone, so the driver fails to build. Include linux/ip.h explicitly to fix this. Signed-off-by:

It was pointed out by Breno Leitao <leitao@linux.vnet.ibm.com> that ixgb would crash on PPC when an IOMMU was in use, if change_mtu was called. It appears to be a pretty simple issue in the driver that wasn't discovered because most systems don't run with an IOMMU. The driver needs to only unmap buffers that are mapped (duh).

When NETIF_F_LLTX is set, the atlx driver will use a private lock. But in recent kernels this implementation seems redundant and can cause problems where AF_PACKET sees things twice. Since NETIF_F_LLTX is marked as deprecated and shouldn't be used in new driver, this patch removes NETIF_F_LLTX and adds a mmiowb before sending packet. I have tested this driver on a Eee PC. It works well. Signed-off-by:

The PHY's aneg is configured and restarted whenever the link is brought up, e.g. when DHCP is started after the kernel has booted. This can take the link down for several seconds while auto-negotiation is redone. If the advertised features haven't changed, then it shouldn't be necessary to bring down the link and start auto-negotiation over again. genphy_config_advert() is enhanced to return 0 when the advertised features haven't been changed and >0 when they have been. genphy_config_aneg() then uses this information to not call genphy_restart_aneg() if there has been no change.

The gabs array in the sctp_tsnmap structure is only used in one place, sctp_make_sack(). As such, carrying the array around in the sctp_tsnmap and thus directly in the sctp_association is rather pointless since most of the time it's just taking up space. Now, let sctp_make_sack create and populate it and then throw it away when it's done. Signed-off-by:

The tsn map currently use is 4K large and is stuck inside the sctp_association structure making memory references REALLY expensive. What we really need is at most 4K worth of bits so the biggest map we would have is 512 bytes. Also, the map is only really usefull when we have gaps to store and report. As such, starting with minimal map of say 32 TSNs (bits) should be enough for normal low-loss operations. We can grow the map by some multiple of 32 along with some extra room any time we receive the TSN which would put us outside of the map boundry. As we close gaps, we can shift the map to rebase it on the latest TSN we've seen. This saves 4088 bytes per association just in the map alone along savings from the now unnecessary structure members.

I noticed sysctl_local_port_range[] and its associated seqlock sysctl_local_port_range_lock were on separate cache lines. Moreover, sysctl_local_port_range[] was close to unrelated variables, highly modified, leading to cache misses. Moving these two variables in a structure can help data locality and moving this structure to read_mostly section helps sharing of this data among cpus. Cleanup of extern declarations (moved in include file where they belong), and use of inet_get_local_port_range() accessor instead of direct access to ports values. Signed-off-by:

Current UDP port allocation is suboptimal. We select the shortest chain to chose a port (out of 512) that will hash in this shortest chain. First, it can lead to give not so ramdom ports and ease give attackers more opportunities to break the system. Second, it can consume a lot of CPU to scan all table in order to find the shortest chain. Third, in some pathological cases we can fail to find a free port even if they are plenty of them. This patch zap the search for a short chain and only use one random seed. Problem of getting long chains should be addressed in another way, since we can obtain long chains with non random ports.
