Push the request_irq function to the end of probe so as
to ensure all the required fields are populated in the event
of an ISR getting executed right after requesting the irq.
Currently while loading the crash kernel a crash was seen as
soon as devm_request_threaded_irq was called. This was due to
n->poll being NULL which is called as part of net_rx_action
function.

The array data is only populated with valid information from userspace
if cmd != SIOCDEVPRIVATE, other cases the array contains garbage on
the stack. The subsequent switch statement acts on a subcommand in
data[0] which could be any garbage value if cmd is SIOCDEVPRIVATE which
seems incorrect to me. Instead, just return EOPNOTSUPP for the case
where cmd == SIOCDEVPRIVATE to avoid this issue.
As a side note, I suspect that the original intention of the code
was for this ioctl to work just for cmd == SIOCDEVPRIVATE (and the
current logic is reversed). However, I don't wont to change the current
semantics in case any userspace code relies on this existing behaviour.

In commit 1c6c6d221e ("mlxsw: spectrum: Mirror certain packets to
CPU") we marked packets that were mirrored to the CPU, so that they
won't be flooded again by the bridge driver.
However, certain packets are trapped in the device's router block, after
passing through the bridge block where they were potentially flooded.
Mark all packets coming from L3 traps, so that they won't be potentially
flooded again by the bridge driver.

Since the skb is attached to the first control block of a fragmented
skb it is possible that the skb could be freed when reclaiming that
control block before all fragments of the skb have been consumed by
the hardware and unmapped.
This commit introduces first_cb and last_cb pointers to the skb
control block used by the driver to keep track of which transmit
control blocks within a transmit ring are the first and last ones
associated with the skb.
It then splits the bcmgenet_free_cb() function into transmit
(bcmgenet_free_tx_cb) and receive (bcmgenet_free_rx_cb) versions
that can handle the unmapping of dma mapped memory and cleaning up
the corresponding control block structure so that the skb is only
freed after the last associated transmit control block is reclaimed.

harmless. If we add more than 288 unicast addresses we will then read

While working on IPv6 route replace I realized we can have a
use-after-free in IPv4 in case the replaced route is offloaded and the
only one using its FIB info.
The problem is that fib_table_insert() drops the reference on the FIB
info of the replaced routes which is eventually freed via call_rcu().
Since the driver doesn't hold a reference on this FIB info it can cause
a use-after-free when it tries to clear the RTNH_F_OFFLOAD flag stored
in fi->fib_flags.
After running the following commands in a loop for enough time with a
KASAN enabled kernel I finally got the below trace.

for shared or non-shared mode. It should be using the ethtool requested
"sh" parameter instead of the current "sh" parameter.
Fix it by passing the "sh" parameter to bnxt_reserve_rings(). For
ethtool, we will pass in the requested "sh" parameter.

.ndo_get_stats64() may not be protected by RTNL and can race with
.ndo_stop() or other ethtool operations that can free the statistics
memory. Fix it by setting a new flag BNXT_STATE_READ_STATS and then
proceeding to read statistics memory only if the state is OPEN. The
close path that frees the memory clears the OPEN state and then waits
for the BNXT_STATE_READ_STATS to clear before proceeding to free the
statistics memory.

The new IPSec offload code introduced a build error:
drivers/net/ethernet/mellanox/mlx5/core/en_accel/ipsec_rxtx.o: In function `mlx5e_ipsec_build_inverse_table':
ipsec_rxtx.c:(.text+0x556): undefined reference
Another patch was added on top to fix the build error, but
that introduced a new bug, as we now use the remainder of
the division rather than the result.
This makes it use the correct helper function instead.
