From 2c77bcb344f589054b2039bddcd32c4f666258b9 Mon Sep 17 00:00:00 2001 From: Guillaume Nault Date: Wed, 15 Jan 2025 12:53:55 +0100 Subject: [PATCH] gre: Prepare ipgre_open() to .flowi4_tos conversion. Use ip4h_dscp() to get the tunnel DSCP option as dscp_t, instead of manually masking the raw tos field with INET_DSCP_MASK. This will ease the conversion of fl4->flowi4_tos to dscp_t, which just becomes a matter of dropping the inet_dscp_to_dsfield() call.
