We need to set/clear the mac address register when the link goes up/down respectively. Without this both ports of a 2-port device can end up with the same mac address in a bonding scenario. The new ql_link_on() and ql_link_off() will also be used in handling certain firmware events. Signed-off-by:

This addes functionality to set/clear the MAC address in the hardware when the link goes up/down. The MAC address register is persistent across function resets. In bonding the same address can bounce from one port to the other. This can cause packets to be delivered to the wrong port. This patch clears the MAC address in the hardware when the link is down and sets it when the link comes up. It was found that pulling/pushing the cable from one port to another causes the same MAC address to be in both ports. The next patch in this series will use this functionality as well. Signed-off-by:

The hardware semaphore covers the configuration register as well as the ICB registers. The ICB high and low regs contain the address of the initialization control block and the config register is used to signal the hardware that a block is ready to be downloaded. Currently we were only protecting the ICB regs. This changes expands to cover the config register as well. Signed-off-by:

There's a bug in addrconf_prefix_rcv() where it won't update the preferred lifetime of an IPv6 address if the current valid lifetime of the address is less than 2 hours (the minimum value in the RA). For example, If I send a router advertisement with a prefix that has valid lifetime = preferred lifetime = 2 hours we'll build this address: 3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000 inet6 2001:1890:1109:a20:217:8ff:fe7d:4718/64 scope global dynamic valid_lft 7175sec preferred_lft 7175sec If I then send the same prefix with valid lifetime = preferred lifetime = 0 it will be ignored since the minimum valid lifetime is 2 hours: 3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000 inet6 2001:1890:1109:a20:217:8ff:fe7d:4718/64 scope global dynamic valid_lft 7161sec preferred_lft 7161sec But according to RFC 4862 we should always reset the preferred lifetime even if the valid lifetime is invalid, which would cause the address to immediately get deprecated. So with this patch we'd see this: 5: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000 inet6 2001:1890:1109:a20:21f:29ff:fe5a:ef04/64 scope global deprecated dynamic valid_lft 7163sec preferred_lft 0sec The comment winds-up being 5x the size of the code to fix the problem. Update the preferred lifetime of IPv6 addresses derived from a prefix info option in a router advertisement even if the valid lifetime in the option is invalid, as specified in RFC 4862 Section 5.5.3e. Fixes an issue where an address will not immediately become deprecated. Reported by Jens Rosenboom. Signed-off-by:Brian Haley <brian.haley@hp.com> Signed-off-by:

The PHY_HALTED state disables phydev->link, but the link will not be updated upon entering PHY_RESUMING. Add a call to phy_read_status() to update the link before entering PHY_RUNNING. If the link is not up at this point, enter the PHY_NOLINK state instead. Also, when transitioning from PHY_RESUMING to PHY_RUNNING, calls to netif_carrier_on() and phydev->adjust_link() are missing. Add the calls similar to the other transitions to PHY_RUNNING. Signed-off-by:

Restrict firmware reset to following cases - o chip rev is NX2031 (firmare doesn't support heartbit). o firmware is dead. o previous attempt to init firmware had failed. o we have got newer file firmware. This speeds up module load tremendously (by upto 8 sec), also avoids downtime for NCSI (management) pass-thru traffic. Signed-off-by:

This reverts commit 73ce7b01. After discovering that we don't listen to gratuitious arps in 2.6.30 I tracked the failure down to this commit. The patch makes absolutely no sense. RFC2131 RFC3927 and RFC5227. are all in agreement that an arp request with sip == 0 should be used for the probe (to prevent learning) and an arp request with sip == tip should be used for the gratitous announcement that people can learn from. It appears the author of the broken patch got those two cases confused and modified the code to drop all gratuitous arp traffic. Ouch! Cc: stable@kernel.org Signed-off-by:

If a socket starts out on a non-TSO route, and then switches to a TSO route, then we will tack on data to the tail of the tx queue even if it started out life as non-TSO. This is suboptimal because all of it will then be copied and checksummed unnecessarily. This patch fixes this by ensuring that skb->ip_summed is set to CHECKSUM_PARTIAL before appending extra data beyond the MSS. Signed-off-by:
