This change moves a multi-line register setting into a function which simplifies reading the flow of the enable function. This also fixes a bug where the enable function was enabling the interrupt twice while trying to update the two interrupt throttle rate thresholds for Rx and Tx.

When the VF driver is unable to communicate with the PF, it just gives up and never tries again. Aside from the obvious character flaw that this shows, it's also a lousy user experience. When PF communications fail, wait five seconds, and try again. And again. Don't give up, little VF driver! Your prince will come!

Acquire NVM, before issuing an AQ read nvm command for X722. We need to acquire the NVM before issuing an AQ read to the NVM otherwise we will get EBUSY from the FW. Also release when done.

This patch introduces a spinlock which is to be used for synchronizing access to VSI's MAC filter list. This patch also synchronizes execution of other codepaths which are accessing VSI's MAC filter list with execution of service_task:sync_vsi_filters. In function i40e_add_vsi, copied out LAA MAC address instead of cloning MAC filter entry because only MAC address is needed to remove MAC VLAN filter from FW/HW.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter/IPVS updates for your net-next tree. Most relevantly, updates for the nfnetlink_log to integrate with conntrack, fixes for cttimeout and improvements for nf_queue core, they are: 1) Remove useless ifdef around static inline function in IPVS, from Eric W. Biederman. 2) Simplify the conntrack support for nfnetlink_queue: Merge nfnetlink_queue_ct.c file into nfnetlink_queue_core.c, then rename it back to nfnetlink_queue.c 3) Use y2038 safe timestamp from nfnetlink_queue. 4) Get rid of dead function definition in nf_conntrack, from Flavio Leitner. 5) Attach conntrack support for nfnetlink_log.c, from Ken-ichirou MATSUZAWA. This adds a new NETFILTER_NETLINK_GLUE_CT Kconfig switch that controls enabling both nfqueue and nflog integration with conntrack. The userspace application can request this via NFULNL_CFG_F_CONNTRACK configuration flag. 6) Remove unused netns variables in IPVS, from Eric W. Biederman and Simon Horman. 7) Don't put back the refcount on the cttimeout object from xt_CT on success. 8) Fix crash on cttimeout policy object removal. We have to flush out the cttimeout extension area of the conntrack not to refer to an unexisting object that was just removed. 9) Make sure rcu_callback completion before removing nfnetlink_cttimeout module removal. 10) Fix compilation warning in br_netfilter when no nf_defrag_ipv4 and nf_defrag_ipv6 are enabled. Patch from Arnd Bergmann. 11) Autoload ctnetlink dependencies when NFULNL_CFG_F_CONNTRACK is requested. Again from Ken-ichirou MATSUZAWA. 12) Don't use pointer to previous hook when reinjecting traffic via nf_queue with NF_REPEAT verdict since it may be already gone. This also avoids a deadloop if the userspace application keeps returning NF_REPEAT. 13) A bunch of cleanups for netfilter IPv4 and IPv6 code from Ian Morris. 14) Consolidate logger instance existence check in nfulnl_recv_config(). 15) Fix broken atomicity when applying configuration updates to logger instances in nfnetlink_log. 16) Get rid of the .owner attribute in our hook object. We don't need this anymore since we're dropping pending packets that have escaped from the kernel when unremoving the hook. Patch from Florian Westphal. 17) Remove unnecessary rcu_read_lock() from nf_reinject code, we always assume RCU read side lock from .call_rcu in nfnetlink. Also from Florian. 18) Use static inline function instead of macros to define NF_HOOK() and NF_HOOK_COND() when no netfilter support in on, from Arnd Bergmann. ==================== Signed-off-by: NDavid S.

Sowmini found hang with rds-ping while testing RDS over TCP. Its a corner case and doesn't happen always. The issue is not reproducible with IB transport.

Commit db6526dc ("RDS: use rds_send_xmit() state instead of RDS_LL_SEND_FULL") which was trying to opportunistically finish the send request in same thread context. But because of above recursive lock hang with RDS TCP, the send work from rds_send_pong() needs to deferred to worker to avoid lock up. Given RDS ping is more of connectivity test than performance critical path, its should be ok even for transport like IB.

At the time of commit fff32699 ("tcp: reflect SYN queue_mapping into SYNACK packets") we had little ways to cope with SYN floods. We no longer need to reflect incoming skb queue mappings, and instead can pick a TX queue based on cpu cooking the SYNACK, with normal XPS affinities. Note that all SYNACK retransmits were picking TX queue 0, this no longer is a win given that SYNACK rtx are now distributed on all cpus.

A dhcp server may provide parameters to a client from a pool of IP addresses and using a shared rootfs, or provide a specific set of parameters for a specific client, usually using the MAC address to identify each client individually. The dhcp protocol also specifies a client-id field which can be used to determine the correct parameters to supply when no MAC address is available. There is currently no way to tell the kernel to supply a specific client-id, only the userspace dhcp clients support this feature, but this can not be used when the network is needed before userspace is available such as when the root filesystem is on NFS. This patch is to be able to do something like "ip=dhcp,client_id_type, client_id_value", as a kernel parameter to enable the kernel to identify itself to the server.

A recent change to the dst_output handling caused a new warning when the call to NF_HOOK() is the only used of a local variable passed as 'dev', and CONFIG_NETFILTER is disabled: net/ipv6/ip6_output.c: In function 'ip6_output': net/ipv6/ip6_output.c:135:21: warning: unused variable 'dev' [-Wunused-variable] The reason for this is that the NF_HOOK macro in this case does not reference the variable at all, and the call to dev_net(dev) got removed from the ip6_output function. To avoid that warning now and in the future, this changes the macro into an equivalent inline function, which tells the compiler that the variable is passed correctly but still unused. The dn_forward function apparently had the same problem in the past and added a local workaround that no longer works with the inline function. In order to avoid a regression, we have to also remove the #ifdef from decnet in the same patch.
