[PATCH 5.15 129/151] bnxt_en: correct offset handling for IPv6 destination address

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alok Tiwari <alok.a.tiwari@oracle.com>

[ Upstream commit 3d3aa9472c6dd0704e9961ed4769caac5b1c8d52 ]

In bnxt_tc_parse_pedit(), the code incorrectly writes IPv6
destination values to the source address field (saddr) when
processing pedit offsets within the destination address range.

This patch corrects the assignment to use daddr instead of saddr,
ensuring that pedit operations on IPv6 destination addresses are
applied correctly.

Fixes: 9b9eb518e338 ("bnxt_en: Add support for NAT(L3/L4 rewrite)")
