Hi Omar,

This looks like two commits jammed together into one. I would split up 
the ci_rx_flex_desc changes from the rest of the fix (the logging 
changes are technically separate but IMO they can go in with the macro 
changes). The flex desc changes in particular would probably also 
require a Fixes: tag and a Cc: stable if the source commit is old enough 
to be in stable releases.

For the macro changes, DPDK is a BSD-3 clause licensed project, so 
technically we cannot use kernel code as it's GPL-licensed. Please do 
not refer to kernel implementation directly.

I do however think it's worth rewriting the Rx status etc code with 
FIELD_GET macros the way you did as that makes the code a lot clearer, 
and better detailed logging is certainly appreciated.

This patch would also benefit from better commit message. Suggested 
rewording:

[patch 1: flex descriptor changes]

net/ice: fix missing type casts for flex descriptors

When ice driver was ported to use the common Rx descriptor format, some 
type casts were missed. Add them.

Fixes: <sha of commit that introduced the issue>
Cc: stable at dpdk.org [possibly - double check if this is needed]

---

[patch 2: macro/logging changes]

net/ice: use macros to get field values

Currently, in ice_check_fdir_programming_status, descriptor fields are 
accessed through direct bit mask manipulation and shifts. The ice driver 
has macros for this, so rewrite the function to use FIELD_GET macros 
instead.
