Subject: [PATCH net-next] net: ethernet: ti: cpsw: drop CPSW_HEADROOM define
Date: Fri, 8 Apr 2022 16:48:38 +0300 [thread overview]
Message-ID: <20220408134838.24761-1-grygorii.strashko@ti.com> (raw)
Since commit 1771afd47430 ("net: cpsw: avoid alignment faults by taking
NET_IP_ALIGN into account") the TI CPSW driver was switched to use correct
define CPSW_HEADROOM_NA to avoid alignment faults, but there are two places
left where CPSW_HEADROOM is still used (without causing issues).
Hence, completely drop CPSW_HEADROOM define and use CPSW_HEADROOM_NA
everywhere to avoid further mistakes in code.
