[ Upstream commit 404dc0fd6fb0bb942b18008c6f8c0320b80aca20 ]
Checksum and length checks are not enabled for IPv4 header with
options and IPv6 with extension headers.
To fix this a change in enum npc_kpu_lc_ltype is required which will
allow adjustment of LTYPE_MASK to detect all types of IP headers.

In rvu_check_rsrc_availability() in case of invalid SSOW req, an incorrect
data is printed to error log. 'req->sso' value is printed instead of
'req->ssow'. Looks like "copy-paste" mistake.
Fix this mistake by replacing 'req->sso' with 'req->ssow'.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

We try to access count + 1 byte from userspace with memdup_user(buffer,
count + 1). However, the userspace only provides buffer of count bytes and
only these count bytes are verified to be okay to access. To ensure the
copied buffer is NUL terminated, we use memdup_user_nul instead.

NIX SQ mode and link backpressure configuration is required for
all platforms. But in current driver this code is wrongly placed
under specific platform check. This patch fixes the issue by
moving the code out of platform check.

The Octeontx2 MAC block (CGX) has separate data paths (SMU and GMP) for
different speeds, allowing for efficient data transfer.
The previous patch which added pause frame configuration has a bug due
to which pause frame feature is not working in GMP mode.
This patch fixes the issue by configurating appropriate registers.
