Subject: [PATCH] net/bnxt: fix issue reading sff8436 sfp eeproms
Date: Fri,  9 Aug 2024 11:21:15 +0100	[thread overview]
Message-ID: <20240809102115.629429-1-pdmorrow@gmail.com> (raw)

From: Peter Morrow <peter@graphiant.com>

If a SFP which supports SFF-8436 is present then
currently the DDM information present in the eeprom
is not read. Furthermore bnxt_get_module_eeprom()
will return -EINVAL for these eeproms since the
length of these eeproms is 512 bytes but we are
only ever selecting 2 pages (256 bytes) to read.
