The Tx head write-back registers are not cleared during an FLR or VF reset. As a result a configuration that had head write-back enabled can leave the registers set after the driver is unloaded. If the next driver loaded doesn't use the write-back registers this can lead to a bad configuration where head write-back is enabled, but the driver didn't request it. To avoid this situation the PF should be resetting the Tx head write-back registers when the VF requests a reset. Signed-off-by:

This change makes it so that the QDE bits are set for a VF before the Rx queues are enabled. As such we avoid head of line blocking in the event that the VF stops cleaning Rx descriptors for whatever reason. Signed-off-by:

Thomas Haller says: ==================== ipv6 addrconf: add IFA_F_NOPREFIXROUTE flag to suppress creation of IP6 routes v1 -> v2: add a second commit, handling NOPREFIXROUTE in ip6_del_addr. v2 -> v3: reword commit messages, code comments and some refactoring. v3 -> v4: refactor, rename variables, add enum v4 -> v5: rebase, so that patch applies cleanly to current net-next/master ==================== Signed-off-by: -

Refactor the deletion/update of prefix routes when removing an address. Now also consider IFA_F_NOPREFIXROUTE and if there is an address present with this flag, to not cleanup the route. Instead, assume that userspace is taking care of this route. Also perform the same cleanup, when userspace changes an existing address to add NOPREFIXROUTE (to an address that didn't have this flag). This is done because when the address was added, a prefix route was created for it. Since the user now wants to handle this route by himself, we cleanup this route. This cleanup of the route is not totally robust. There is no guarantee, that the route we are about to delete was really the one added by the kernel. This behavior does not change by the patch, and in practice it should work just fine. Signed-off-by:

When adding/modifying an IPv6 address, the userspace application needs a way to suppress adding a prefix route. This is for example relevant together with IFA_F_MANAGERTEMPADDR, where userspace creates autoconf generated addresses, but depending on on-link, no route for the prefix should be added.

This patch cleans-up wake-on-lan code in the following ways: 1) Removes some driver hacks in be_cmd_get_acpi_wol_cap() that were based on incorrect assumptions. 2) Uses the adapter->wol_en and wol_cap variables for checking if WoL is supported and enabled on an interface instead of referring to the exclusion list via the macro be_is_wol_supported() Signed-off-by:

Instead, use the tail of the RXQ to pick the associated RXQ entry This fix is required in preparation for supporting RXQ lengths greater than 1K. For such queues, the frag index in the RX-compl entry is not valid as it is only a 10 bit entry not capable of addressing RXQs longer than 1K. Signed-off-by:

An earlier commit (f25b119c "Fix error messages while driver load for VFs") incorrectly set the adapter->cmd_privileges value for VFs (in a multi-channel config) to MAX_PRIVILEGES. This causes FW cmd failures and avoidable error logs when certian cmds are issued by a VF. Also, move the multi-channel hack to be_cmds.c inside be_cmd_get_fn_privileges() routine.

An ndo_set_mac_addr() call may be issued for a mac-addr that is already active on an interface. If so, silently ignore the request. Sending such a request to the FW, causes a "mac collision" error. The error is harmless but is avoidable noise in the kernel log. Signed-off-by:

Skyhawk-R FW does not support SET/GET_EXT_FAT_CAPABILITIES cmds via which FW logging level can be controlled. Also, the hack used in BE3 to control FW logging level via the ethtool interface is not needed in Skyhawk-R. This patch also cleans up this code by moving be_set/get_fw_log_level() routines to be_cmds.c where they belong. Signed-off-by:

Instead of introducing Makefile/Kconfig hacks, build this code as a separate module referenced from both ieee802154 and bluetooth modules.

Currently, we don't rename the upper/lower_ifc symlinks in /sys/class/net/*/ , which might result stale/duplicate links/names. Fix this by adding netdev_adjacent_rename_links(dev, oldname) which renames all the upper/lower interface's links to dev from the upper/lower_oldname to the new name. We don't need a rollback because only we control these symlinks and if we fail to rename them - sysfs will anyway complain. Reported-by:
