Subject: [PATCH net] octeontx2-af: nix: Fix TX vtag upper bits programming
Date: Tue, 15 Sep 2026 13:00:58 +0530 [thread overview]
Message-ID: <20260915073058.992915-1-rkannoth@marvell.com> (raw)
From: Subbaraya Sundeep <sbhatta@marvell.com>
The upper bits of the vtag value above bit 47 were not written to
NIX_AF_TX_VTAG_DEFX_DATA, causing incorrect TX VLAN tag insertion
when extended vtag fields are used.
Fixes: 9a946def264d ("octeontx2-af: Modify nix_vtag_cfg mailbox to support TX VTAG entries")
