The vlan configuration is not restored after interface down/up sequence.
Steps to check:
# ip link add link eth0 name eth0.100 type vlan id 100
# ifconfig eth0 down
# ifconfig eth0 up
This patch fixes it, restoring vlan ALE entries on .ndo_open().

The ndo_start_xmit() methods should return a 'netdev_tx_t', not

tcp: improve delivered counts in SCM_TSTAMP_ACK
Currently delivered and delivered_ce in OPT_STATS of SCM_TSTAMP_ACK do
not fully reflect the current ack being timestamped. Also they are not
in sync as the delivered count includes packets being sacked and some of
cumulatively acked but delivered_ce includes none.
This patch series updates tp->delivered and tp->delivered_ce together to
keep them in sync. It also moves generating SCM_TSTAMP_ACK to later in
tcp_clean_rtx_queue() to reflect packets being cumulatively acked up
until the current skb for sack-enabled connections.

Currently tp->delivered is updated with sacked packets but not
cumulatively acked when SCP_TSTAMP_ACK is timestamped. This patch moves
a tcp_ack_tstamp() call in tcp_clean_rtx_queue() to later in the loop so
that when a skb is fully acked OPT_STATS of SCM_TSTAMP_ACK will include
the current skb in the delivered count. When not fully acked
tcp_ack_tstamp() is a no-op and there is no change in behavior.

Prior to this patch mlx5e tls rx handler was called unconditionally on
all rx frames and the decision whether a frame is a valid tls record
is done inside that function. A function call can be expensive especially
for regular rx packet rate. To avoid this, check the tls validity before
jumping into the tls rx handler.
While at it, split between kTLS device offload rx handler and FPGA tls rx
handler using a similar method.

Implement the RX resync procedure, using the TLS async resync API.

This requires SW intervention to update the HW context and get it

This patch adds support for asynchronous resynchronization in tls_device.
Async resync follows two distinct stages:
1. The NIC driver indicates that it would like to resync on some TLS
record within the received packet (P), but the driver does not
know (yet) which of the TLS records within the packet.
At this stage, the NIC driver will query the device to find the exact
TCP sequence for resync (tcpsn), however, the driver does not wait
for the device to provide the response.
2. Eventually, the device responds, and the driver provides the tcpsn
within the resync packet to KTLS. Now, KTLS can check the tcpsn against
any processed TLS records within packet P, and also against any record
that is processed in the future within packet P.
The asynchronous resync path simplifies the device driver, as it can
save bits on the packet completion (32-bit TCP sequence), and pass this
information on an asynchronous command instead.

Implement driver support for the kTLS RX HW offload feature.
Resync support is added in a downstream patch.
New offload contexts post their static/progress params WQEs
over the per-channel async ICOSQ, protected under a spin-lock.
The Channel/RQ is selected according to the socket's rxq index.
Feature is OFF by default. Can be turned on by:
$ ethtool -K <if> tls-hw-rx-offload on
A new TLS-RX workqueue is used to allow asynchronous addition of
steering rules, out of the NAPI context.
It will be also used in a downstream patch in the resync procedure.

Better separate the code into c/h files, so that kTLS internals
are exposed to the corresponding non-accel flow as follows:
- Necessary datapath functions are exposed via ktls_txrx.h.
- Necessary caps and configuration functions are exposed via ktls.h,
which became very small.
In addition, kTLS internal code sharing is done via ktls_utils.h,
which is not exposed to any non-accel file.
Add explicit WQE structures for the TLS static and progress
params, breaking the union of the static with UMR, and the progress
with PSV.
Generalize the API as a preparation for TLS RX offload support.
Move kTLS TX-specific code to the proper file.
