The new nic_common.h contains the inlines for NIC-type function dispatch,
declarations for NIC-generic functions in nic.c, and other similar NIC-
generic functionality. Retained in nic.h are NIC-specific declarations
such as the siena and ef10 nic_data structs and various farch functions.
The EF100 driver will thus include nic_common.h but not nic.h.

Saeed Mahameed says:
====================
mlx5-tls-2020-06-26
1) Improve hardware layouts and structure for kTLS support
2) Generalize ICOSQ (Internal Channel Operations Send Queue)
Due to the asynchronous nature of adding new kTLS flows and handling
HW asynchronous kTLS resync requests, the XSK ICOSQ was extended to
support generic async operations, such as kTLS add flow and resync, in
addition to the existing XSK usages.
3) kTLS hardware flow steering and classification:
The driver already has the means to classify TCP ipv4/6 flows to send them
to the corresponding RSS HW engine, as reflected in patches 3 through 5,
the series will add a steering layer that will hook to the driver's TCP
classifiers and will match on well known kTLS connection, in case of a
match traffic will be redirected to the kTLS decryption engine, otherwise
traffic will continue flowing normally to the TCP RSS engine.
3) kTLS add flow RX HW offload support
New offload contexts post their static/progress params WQEs
(Work Queue Element) to communicate the newly added kTLS contexts
over the per-channel async ICOSQ.
The Channel/RQ is selected according to the socket's rxq index.
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.
Feature is OFF by default. Can be turned on by:
$ ethtool -K <if> tls-hw-rx-offload on
4) Added mlx5 kTLS sw stats and new counters are documented in
Documentation/networking/tls-offload.rst
rx_tls_ctx - number of TLS RX HW offload contexts added to device for
decryption.
rx_tls_ooo - number of RX packets which were part of a TLS stream
but did not arrive in the expected order and triggered the resync
procedure.
rx_tls_del - number of TLS RX HW offload contexts deleted from device
(connection has finished).
rx_tls_err - number of RX packets which were part of a TLS stream
but were not decrypted due to unexpected error in the state machine.
5) Asynchronous RX resync
a. 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.
b. 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.

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.
