packet: remove handling of tx_ring
Remove handling of tx_ring in prb_setup_retire_blk_timer
for TPACKET_V3 because init_prb_bdqc is called only for zero tx_ring
and thus prb_setup_retire_blk_timer for zero tx_ring only.
And also in functon init_prb_bdqc there is no usage of tx_ring.
Thus removing tx_ring from init_prb_bdqc.

drivers/net: remove all references to obsolete Ethernet-HOWTO
This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it. And there is
no value in anyone else taking over updating it either.
However the references to it continue to spread as boiler plate text
from one Kconfig file into the next. We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.
No code is changed in this commit, just Kconfig help text.

The first iteration of the dwmac-rk support did access an intermediate

the driver trying to set the rate of a non-existent clock when the soc
and not some external source provides the phy clock for RMII phys.

BPF offers another way to generate latency histograms. We attach
kprobes at trace_preempt_off and trace_preempt_on and calculate the

The first array is used to store the start time stamp. The key is the
CPU id. The second array stores the log2(time diff). We need to use
static allocation here (array and not hash tables). The kprobes
hooking into trace_preempt_on|off should not calling any dynamic

bridge: multicast: start querier timer when running user-space stp
When STP is running in user-space and querier is configured, the
querier timer is not started when a port goes to a non-blocking state.
This patch unifies the user- and kernel-space stp multicast port enable
path and enables it in all states different from blocking. Note that when a
port goes in BR_STATE_DISABLED it's not enabled because that is handled
in the beginning of the port list loop.

groups IDs than 32.
This new NETLINK_LIST_MEMBERSHIPS option takes a pointer to __u32 and the

socket, and the required array size is returned in optlen. Hence,
user-space can retry with a properly sized array in case it was too small.

The following patchset contains a final Netfilter pull request for net-next
4.2. This mostly addresses some fallout from the previous pull request, small
netns updates and a couple of new features for nfnetlink_log and the socket
match that didn't get in time for the previous pull request. More specifically
they are:
1) Add security context information to nfnetlink_queue, from Roman Kubiak.
2) Add support to restore the sk_mark into skb->mark through xt_socket,
from Harout Hedeshian.
3) Force alignment of 16 bytes of per cpu xt_counters, from Eric Dumazet.

into a separated file.
5) Move the IPv6 code in br_netfilter into a separated file.
6) Remove unused RCV_SKB_FAIL() in nfnetlink_queue and nfetlink_log, from Eric
Biederman.
7) Two liner to simplify netns logic in em_ipset_match().
8) Add missing includes to net/net_namespace.h to avoid compilation problems
that result from not including linux/netfilter.h in netns headers.
9) Use a forward declaration instead of including linux/proc_fs.h from
netns/netfilter.h
10) Add a new linux/netfilter_defs.h to replace the linux/netfilter.h inclusion
in netns headers.
11) Remove spurious netfilter.h file included in the net tree, also from Eric

The remove_advertising() and remove_advertising_complete() functions

remove_advertising() is refactored to use the new dynamic advertising

====================
This series contains updates to fm10k only.
Alex provides two fixes for the fm10k, first folds the fm10k_pull_tail()
call into fm10k_add_rx_frag(), this way the fragment does not have to be
modified after it is added to the skb. The second fixes missing braces
to an if statement.
The remaining patches are from Jacob which contain improvements and fixes
for fm10k. First fix makes it so that invalid address will simply be
skipped and allows synchronizing the full list to proceed with using
iproute2 tool. Fixed a possible kernel panic by using the correct
transmit timestamp function. Simplified the code flow for setting the
IN_PROGRESS bit of the shinfo for an skb that we will be timestamping.
Fix a bug in the timestamping transmit enqueue code responsible for a
NULL pointer dereference and invalid access of the skb list by freeing
the clone in the cases where we did not add it to the queue. Update the
PF code so that it resets the empty TQMAP/RQMAP regirsters post-VFLR to
prevent innocent VF drivers from triggering malicious driver events.
The SYSTIME_CFG.Adjust direction bit is actually supposed to indicate
that the adjustment is positive, so fix the code to align correctly with
the hardware and documentation. Cleanup local variable that is no longer
used after a previous refactor of the code. Fix the code flow so that we
actually clear the enabled flag as part of our removal of the LPORT.

fm10k: fix iov_msg_lport_state_pf issue
When a VF issues an LPORT_STATE request to enable a port that is already
enabled, the PF will first disable the VF LPORT. Then it should
re-enable the VF again with the new requested settings. This ensures
that any switch rules are cleared by deleting the LPORT on the switch.
However, the flow is bugged because we actually check if the VF is
enabled at the end, and thus don't re-enable it. Fix the flow so that we
actually clear the enabled flags as part of our removal of the LPORT.

fm10k: remove err_no reference in fm10k_mbx.c
The reference to err_no was left around after a previous code refactor.
We never use the value, and it doesn't seem to be used in side a hidden
macro reference. Discovered via cppcheck.
