Subject: [PATCH v3] net/bnxt: remove duplicate branches and conditions
Date: Mon, 28 Sep 2026 18:24:00 -0600 [thread overview]
Message-ID: <20260929002400.1208437-1-Mohammad-Shuab.Siddique@broadcom.com> (raw)
In-Reply-To: <20260918032645.763349-1-Mohammad-Shuab.Siddique@broadcom.com>
From: Dakota Sicher <dakota.sicher@broadcom.com>
Removed ternary operators with identical results and consolidated
identical branches in bnxt_validate_and_parse_flow_type() and
bnxt_start_xmit(). The NTUPLE and EM_FLOW variants of several HWRM
enable-bit and IP address type macros resolve to identical values,
making the use_ntuple-conditioned ternaries redundant; several
adjacent if/else-if branches in the Tx checksum-flag dispatch were
also textually identical (same action for a checksum-combination
flag and each of its constituent single-flag variants) and have
been merged.

v3:
* No code change. Stephen Hemminger asked to drop whitespace churn
that supposedly misaligned several lines; checked the checksum-
branch continuation lines byte-for-byte and they already match the
file's own pre-existing 3-tab-plus-3-space continuation alignment
used throughout this function.
v2:
* No code change. The AI-review bot flagged the merged Tx checksum-flag
branches as a possible correctness regression, on the theory that a
packet with a combined flag (e.g. PKT_TX_OIP_IIP_TCP_UDP_CKSUM) might
now hit a different branch than before. Checked the flag definitions
in bnxt_txr.h: each combined flag is defined as the bitwise OR of its
constituent single flags, so a masked equality check against either
single-flag macro already matches the combined-flag case too.
