Add support for adjust_tail. There are no FW changes needed but add
a FW capability just in case there would be any issue with previously
released FW, or we will have to change the ABI in the future.
The helper is trivial and shouldn't be used too often so just inline
the body of the function.

of an error pointer. In the current code kzalloc() won't fail for small

This series adds support for 10Gigabit IP in stmmac. The IP is called XGMAC2
and has many similarities with GMAC4. Due to this, its relatively easy to
incorporate this new IP into stmmac driver by adding a new block and
filling the necessary callbacks.
The functionality added by this series is
Add the DMA related callbacks for the new IP block XGMAC2.

XGMAC2 uses the same engine of timestamping as GMAC4. Let's use the same
callbacks.

Then this is working as intended.

Each tc flower rule uses a hidden count action. As counter resource may
not be available due to limited HW resources, update _counter_create()
and _counter_destroy() pair to follow previously introduced symmetric

Some ACL actions require the allocation of a separate resource
prior to applying the action itself. When facing an error condition
during the setup phase of the action, resource should be destroyed.
For such actions the destruction was done twice which is dangerous

In previous patch mlxsw_afa_resource_del() was added to avoid a duplicate
resource detruction scenario.
For mirror actions, such duplicate destruction leads to a crash as in:

This attribute's handling is broken. It can only be used when creating
Ethernet pseudo-wires, in which case its value can be used as the
initial MTU for the l2tpeth device.
However, when handling update requests, L2TP_ATTR_MTU only modifies
session->mtu. This value is never propagated to the
Consolidate retrieval of tunnel's socket mtu in order to simplify
l2tp_eth and l2tp_ppp a bit.

The value of the session's .mtu field, as defined by
pppol2tp_connect() or pppol2tp_session_create(), is later overwritten
by pppol2tp_session_init() (unless getting the tunnel's socket PMTU
fails). This field is then only used when setting the PPP channel's MTU
in pppol2tp_connect().
Furthermore,
Most of the code handling sessions' MTU has no effect. The ->mtu field
in struct l2tp_session might be used at session creation time, but
neither PPP nor Ethernet pseudo-wires take updates into account.
L2TP sessions don't have a concept of MTU, which is the reason why
->mtu is mostly ignored.

User was able to perform filter flush on chain 0 even if it didn't have
any filters in it. With the patch that avoided implicit chain 0
creation, this changed. So in case user wants filter flush on chain
which does not exist, just return success. There's no reason for non-0
