Subject: [PATCH v1 1/4] net/axgbe: fix MAC TCR speed select field width
Date: Fri, 27 Mar 2026 17:50:03 +0530 [thread overview]
Message-ID: <20260327122011.1534-1-ashokkumar.natarajan@amd.com> (raw)
The MAC Transmit Configuration Register (TCR) speed select (SS)
field is defined as 2 bits wide, while the hardware specification
defines this field as 3 bits to encode all supported MAC speeds.
Update the SS field width to 3 bits to match the hardware
specification and avoid truncation of speed select values.
Fixes: 69e209be5464 ("net/axgbe: add register map and related macros")
