If a TX hang occurs, we attempt to recover by incrementally resetting.
If we're starved for CPU time, it's possible the reset doesn't actually
complete (or even fire) before another tx_timeout fires causing us to
fly through the different resets without actually doing them.

This adds a bit to set and check if a timeout recovery is already
pending and, if so, bail out of tx_timeout.  The bit will get cleared at
the end of i40e_rebuild when reset is complete.

The i40e driver complains about unprivileged VFs trying to configure
promiscuous mode each time a VF reset occurs. This isn't the fault of
the poor VF driver - the PF driver itself is making the request.

To fix this, skip the privilege check if the request is to disable all
promiscuous activity. This gets rid of the bogus message, but doesn't
affect privilege checks, since we really only care if the unprivileged
VF is trying to enable promiscuous mode.

net: aquantia: add rx-flow filter support

In this patchset the rx-flow filters functionality and vlan filter offloads
are implemented.

The rules in NIC hardware have fixed order and priorities.
To support this, the locations of filters from ethtool perspective are also fixed:

* Locations 0 - 15 for VLAN ID filters
* Locations 16 - 31 for L2 EtherType and PCP filters
* Locations 32 - 39 for L3/L4 5-tuple filters (locations 32, 36 for IPv6)

L2 EtherType filters allows to filter packet by EtherType field or
both EtherType and User Priority (PCP) field of 802.1Q.
UserPriority (vlan) parameter must be accompanied by mask 0x1FFF. That
is to distinguish VLAN filter from L2 Ethertype filter with
UserPriority since both User Priority and VLAN ID are passed in the
same 'vlan' parameter.

Example:
To add a filter that directs IP4 packess of priority 3 to queue 3:
ethtool -N <ethX> flow-type ether proto 0x800 vlan 0x600 m 0x1FFF \
action 3 loc 16

The VLAN filter (VLAN id) is compared against 16 filters.

User Priority and VLAN ID are passed in the same 'vlan' parameter.
Flow type may be any as  it is not matched for VLAN filter.
Due to fixed order of the rules in the NIC, the location 0-15 are
reserved for vlan filters.

Signed-off-by: David S. Miller <davem@davemloft.net>

Each slave has it's own receive timestamp filter. But cpts rx/tx
timestamp enable flags are used to allow ts retrieve only for one
user. This limitation causes data path redundancy and setting overlap
if cpsw module is in dual-mac mode for instance.

If rx ts is enabled only for one port - the second interface must expect
every incoming packet to be PTP packet w/o absolutely any reason, and if
it's PTP - do unneeded stuff, as rx filter for second port is not set
and cpts fifo is not supposed to contain appropriate ts event.
That's not correct.

So, to fix control overlap and avoid redundant CPU cycles, the patch
splits rx/tx ts enable flags between network devices. After the patch,
PTP timestamping still should be used for only one port (or PTP id
counter has to be different for both ports as cpts IP is common).

The overflow event is running with 1 jiffy in case if txq is not
empty, but it can be emptied completely only if next tx event
consumes skb or deletes staled skb from the txq. In case of staled
skb, that can happen for some unpredictable reason (the ts event was
lost or timed out), the overflow event can be generated quite long
time consuming CPU w/o reason before next tx event happens. To avoid
it, purge txq before increasing overflow event rate.

sctp: add support for sk_reuseport

sctp sk_reuseport allows multiple socks to listen on the same port and
addresses, as long as these socks have the same uid. This works pretty
much as TCP/UDP does, the only difference is that sctp is multi-homing
and all the bind_addrs in these socks will have to completely matched,
otherwise listen() will return err.

The below is when 5 sockets are listening on 172.16.254.254:6400 on a
server, 26 sockets on a client connect to 172.16.254.254:6400 and each
may be processed by a different socket on the server which is selected
by hash(lport, pport, paddr) in reuseport_select_sock():

Pull x86 fixes from Thomas Gleixner:
 "A set of x86 fixes:

   - Cure the LDT remapping to user space on 5 level paging which ended
     up in the KASLR space

   - Remove LDT mapping before freeing the LDT pages

   - Make NFIT MCE handling more robust

   - Unbreak the VSMP build by removing the dependency on paravirt ops

   - Support broken PIT emulation on Microsoft hyperV

   - Don't trace vmware_sched_clock() to avoid tracer recursion

   - Remove -pipe from KBUILD CFLAGS which breaks clang and is also
     slower on GCC

   - Trivial coding style and typo fixes"
