Several Lenovo users have reported problems with their Sierra
Wireless EM7455 modem. The driver has loaded successfully and
the MBIM management channel has appeared to work, including
establishing a connection to the mobile network. But no frames
have been received over the data interface.

The problem affects all EM7455 and MC7455, and is assumed to
affect other modems based on the same Qualcomm chipset and
baseband firmware.

Testing narrowed the problem down to what seems to be a
firmware timing bug during initialization. Adding a short sleep
while probing is sufficient to make the problem disappear.
Experiments have shown that 1-2 ms is too little to have any
effect, while 10-20 ms is enough to reliably succeed.

The interrupt worker code for the enc28j60 relies only on the TXIF flag to
determinate if the packet transmission was completed. However the datasheet
specifies in section 12.1.3 that TXERIF will clear the TXRTS after a
transmit abort. Also in section 12.1.4 that TXIF will be set
when TXRTS transitions from '1' to '0'. Therefore the TXIF flag is enabled
during transmission errors.

This causes a race condition, since the worker code will invoke
enc28j60_tx_clear() -> netif_wake_queue(), potentially invoking the
ndo_start_xmit function to send a new packet. The enc28j60_send_packet function
uses a workqueue that invokes enc28j60_hw_tx(). In between this function is
called, the worker from the interrupt handler will enter the path for error
handler because of the TXERIF flag, causing to invoke enc28j60_tx_clear() again
and releasing the packet scheduled for transmission, causing a kernel crash with
due a NULL pointer.

These crashes due a NULL pointer were observed under stress conditions of the
device. A BUG_ON() sequence was used to validate the issue was fixed, and has
been running without problems for 2 years now.

People who use PACKET_FANOUT_HASH want a symmetric hash, meaning that
they want packets going in both directions on a flow to hash to the
same bucket.

The core kernel SKB hash became non-symmetric when the ipv6 flow label
and other entities were incorporated into the standard flow hash order
to increase entropy.

But there are no users of PACKET_FANOUT_HASH who want an assymetric
hash, they all want a symmetric one.

Therefore, use the flow dissector to compute a flat symmetric hash
over only the protocol, addresses and ports.  This hash does not get
installed into and override the normal skb hash, so this change has
no effect whatsoever on the rest of the stack.

The default fallback function used by mlx5e select queue can return
any TX queues in range [0..dev->num_real_tx_queues).

The current implementation assumes that the fallback function returns
a number in the range [0.. number of channels).  Actually
dev->num_real_tx_queues = (number of channels) * dev->num_tc;
which is more than the expected range if num_tc is configured and could
lead to crashes.

To fix this we test if num_tc is not configured we can safely return the
fallback suggestion, if not we will reciprocal_scale the fallback
result and normalize it to the desired range.

ip_skb_dst_mtu uses skb->sk, assuming it is an AF_INET socket (e.g. it
calls ip_sk_use_pmtu which casts sk as an inet_sk).

However, in the case of UDP tunneling, the skb->sk is not necessarily an
inet socket (could be AF_PACKET socket, or AF_UNSPEC if arriving from
tun/tap).

OTOH, the sk passed as an argument throughout IP stack's output path is
the one which is of PMTU interest:
 - In case of local sockets, sk is same as skb->sk;
 - In case of a udp tunnel, sk is the tunneling socket.

Fix, by passing ip_finish_output's sk to ip_skb_dst_mtu.
