Hi, From: Itamar Gozlan <[email protected]> Sent: Sunday, October 27, 2024 6:14 PM To: Itamar Gozlan; Hamdan Agbariya; NBU-Contact-Thomas Monjalon (EXTERNAL); Suanming Mou; Dariusz Sosnowski; Slava Ovsiienko; Bing Zhao; Ori Kam; Matan Azrad; Erez Shitrit Cc: [email protected]; [email protected] Subject: [v2] net/mlx5/hws: in NAT64 fix TC to TOS fields mapping
From: Hamdan Igbaria <[email protected]> In IPv6 to IPv4 scenario when copying the TC field to the TOS[DSCP:6 bits, ECN: 2 bits] field the mapping of the fields get set wrongly, since the destination field of TOS is defined as 2 split fields of DSCP and ECN. In IPv4 to IPv6 we don't have this issue since both the source field of TOS and destination field of TC defined as 8 bits. Example to the problematic case of IPv6 to IPv4, TOS to TC mapping: TC=[abcdefgh], it should be mapped to TOS=[DSCP=abcdef, ECN=gh], but instead it was mapped as follow TOS=[DSCP=cdefgh, ECN=ab].
