Lower level functions are properly reporting errors, and higher-level functions are correctly responding to errors, but the errors aren't actually getting through. Typically, the middle-manager function seems to want to shield its boss from any bad news. This change fixes a panic if the driver is unable to enable MSI-X or is unable to acquire enough vectors.

The firmware has added additional status information to allow software to determine if the APP priority for FCoE/iSCSI/FIP is valid or not in CEE DCBX mode. This patch adds to support those additional checks and will only add applications to the software table that have oper and sync bits set without any error.

When using something like "ip maddr add ..." to add another unicast mac address to the netdev, the mac address comes into the set_rx_mode handler in the multicast list whether it is a unicast or multicast address. This was confusing the code when it was trying to search for addresses that needed to be deleted from the VSI, because it was looking for the VSI unicast address in the netdev unicast list. The result was that a new unicast address would get added to the VSI list and then immediately removed, and would never actually make it down into the hardware. This patch removes the separation from unicast and multicast in the search for filters to be deleted. It also simplifies the logic a little with a jump to the bottom of the loop when an address is found. Now it doesn't matter which netdev list the address is hiding in, we'll check them all.

Previously, the driver could call this function and have only true/false returned, but false could mean multiple things like failure to read or link was down. This change allows the caller to get all return values in the call chain bubbled back to the source, which keeps information about failures from being lost. Also, in some unlikely scenarios, the firmware can become slow to respond to admin queue (AQ) queries for link state. Should the AQ time out, the driver can detect the state and avoid a link change when there may have been none. Change-ID: Ib2ac38407b7880750fb891b392fa77457fe6c21c Signed-off-by:

During early development, we added the function name to all of the error strings to make debugging simpler. Now that we've released the driver, our users should have more comprehensible error messages. So tear the roof off and give up the __func__. Ow.

In ethtool, there is a possibility of speed getting set to 0 if advertise is set to 0 (which it is when autoneg is disabled). We never want this to happen as the firmware will actually attempt to set the speed to 0 sending link down, so add an extra check to make sure this doesn't happen.

There was a possibility where the asq_last_status could get through without update and thus report a previous error. I don't think we've actually seen this happen, but this patch will help make sure it doesn't. Change-ID: I9e33927052a5ee6ea21f80b66d4c4b76c2760b17 Signed-off-by:

Explicitly stop the rings belonging to each VF when disabling SR-IOV. Even though the VFs were gone, and the associated VSIs were removed, the rings were not stopped, and in some circumstances the hardware would continue to access the memory formerly used by the rings, causing memory corruption or DMAR errors, both of which would lead to general malaise of the kernel. To relieve this condition, explicitly stop all the rings associated with each VF before releasing its resources. Change-ID: I78c05d562c66e7b594b7e48d67860f49b3e5b6ec Signed-off-by:

The driver was disabling Wake-on-LAN by default and waiting for the user to expressly turn it on. This patch has the driver turning on WoL from the start if enabled in the hardware config, which matches the behavior of our other drivers.

In layer2 mode of the qeth driver, MAC address lists from struct net_device require mapping to the OSA-card. The existing implementation is inefficient for lists with more than several MAC addresses, since for every ndo_set_rx_mode callback it removes all MAC addresses first, and then registers the current MAC address list. This patch changes implementation of ndo_set_rx_mode callback in qeth, only performing hardware registration/removal for new/deleted addresses. To shorten lookup of MAC addresses registered addresses are kept in a hashtable instead of a linear list. Signed-off-by:

Next 3 handle the source address lookup for raw and datagram sockets bound to a VRF device. The conversion to the get_saddr op also fixes locally originated TCP packets showing up at the VRF device. The use of the FLOWI_FLAG_L3MDEV_SRC flag in ip_route_connect_init was causing locally generated packets to skip the VRF device. v2 - rebased to top of net-next per device delete fix and hash based multipath patches ==================== Signed-off-by: -
