Since est_fetch_counters() is called from BH context from timer

Most qdiscs use per cpu counters and are immune to the problem,

When the frame check sequence (FCS) is split across the last two frames
of a fragmented packet, part of the FCS gets counted twice, once when
subtracting the FCS, and again when subtracting the previously received
data.
For example, if 1602 bytes are received, and the first fragment contains
the first 1600 bytes (including the first two bytes of the FCS), and the
second fragment contains the last two bytes of the FCS:
'skb->len == 1600' from the first fragment
size = lstatus & BD_LENGTH_MASK; # 1602
size -= ETH_FCS_LEN; # 1598
size -= skb->len; # -2
Since the size is unsigned, it wraps around and causes a BUG later in
the packet handling, as shown below:

so we have to resize skb array when we change tx_queue_len.
Other qdiscs which read tx_queue_len are fine because they
all save it to sch->limit or somewhere else in qdisc during init.
They don't have to implement this, it is nicer if they do so
that users don't have to re-configure qdisc after changing
tx_queue_len.

Previously we simply read dev->tx_queue_len, after pfifo_fast
switches to skb array, we need this API to resize the skb array
when we change dev->tx_queue_len.
To avoid handling race conditions with TX BH, we need to
deactivate all TX queues before change the value and bring them

If a sk_v6_rcv_saddr is !IPV6_ADDR_ANY and !IPV6_ADDR_MAPPED, it
implicitly implies it is an ipv6only socket. However, in inet6_bind(),
this addr_type checking and setting sk->sk_ipv6only to 1 are only done
after sk->sk_prot->get_port(sk, snum) has been completed successfully.
This inconsistency between sk_v6_rcv_saddr and sk_ipv6only confuses
the 'get_port()'.
In particular, when binding SO_REUSEPORT UDP sockets,
udp_reuseport_add_sock(sk,...) is called. udp_reuseport_add_sock()
checks "ipv6_only_sock(sk2) == ipv6_only_sock(sk)" before adding sk to
sk2->sk_reuseport_cb. In this case, ipv6_only_sock(sk2) could be
1 while ipv6_only_sock(sk) is still 0 here. The end result is,
reuseport_alloc(sk) is called instead of adding sk to the existing
sk2->sk_reuseport_cb.
It can be reproduced by binding two SO_REUSEPORT UDP sockets on an
IPv6 address (!ANY and !MAPPED). Only one of the socket will
receive packet.
The fix is to set the implicit sk_ipv6only before calling get_port().
The original sk_ipv6only has to be saved such that it can be restored
in case get_port() failed. The situation is similar to the
inet_reset_saddr(sk) after get_port() has failed.
Thanks to Calvin Owens <calvinowens@fb.com> who created an easy
reproduction which leads to a fix.

RTM_{NEW,SET}LINK already allow operations on other network namespaces
by identifying the target network namespace through IFLA_NET_NS_{FD,PID}
properties. This is done by looking for the corresponding properties in
do_setlink(). Extend do_setlink() to also look for the IFLA_IF_NETNSID
property. This introduces no functional changes since all callers of
do_setlink() currently block IFLA_IF_NETNSID by reporting an error before
they reach do_setlink().
This introduces the helpers:
static struct net *rtnl_link_get_net_by_nlattr(struct net *src_net, struct
nlattr *tb[])
static struct net *rtnl_link_get_net_capable(const struct sk_buff *skb,
struct net *src_net,
struct nlattr *tb[], int cap)
to simplify permission checks and target network namespace retrieval for
RTM_* requests that already support IFLA_NET_NS_{FD,PID} but get extended
to IFLA_IF_NETNSID. To perserve backwards compatibility the helpers look
for IFLA_NET_NS_{FD,PID} properties first before checking for
IFLA_IF_NETNSID.

efx_ptp_want_txqs() and efx_ptp_channel_type (a struct) are only used
in ptp.c. In all cases these symbols should be static.

40GbE Intel Wired LAN Driver Updates 2018-01-26
This series contains updates to i40e and i40evf.
Michal updates the driver to pass critical errors from the firmware to
the caller.
Patryk fixes an issue of creating multiple identical filters with the
same location, by simply moving the functions so that we remove the
existing filter and then add the new filter.
Paweł adds back in the ability to turn off offloads when VLAN is set for
the VF driver. Fixed an issue where the number of TC queue pairs was
exceeding MSI-X vectors count, causing messages about invalid TC mapping
and wrong selected Tx queue.
Alex cleans up the i40e/i40evf_set_itr_per_queue() by dropping all the
unneeded pointer chases. Puts to use the reg_idx value, which was going
unused, so that we can avoid having to compute the vector every time
throughout the driver.
Upasana enable the driver to display LLDP information on the vSphere Web
Client by exposing DCB parameters.
Alice converts our flags from 32 to 64 bit size, since we have added
more flags.
Dave implements a private ethtool flag to disable the processing of LLDP
packets by the firmware, so that the firmware will not consume LLDPDU
and cause them to be sent up the stack.
Alan adds a mechanism for detecting/storing the flag for processing of
LLDP packets by the firmware, so that its current state is persistent
across reboots/reloads of the driver.
Avinash fixes kdump with i40e due to resource constraints. We were
enabling VMDq and iWARP when we just have a single CPU, which was
starving kdump for the lack of IRQs.
Jake adds support to program the fragmented IPv4 input set PCTYPE.
Fixed the reported masks to properly report that the entire field is
masked, since we had accidentally swapped the mask values for the IPv4
addresses with the L4 port numbers.
