With a little extra digging I found out that the 6.12 NXP branch does properly support jumbo frames.

LF-14857-8 net: enetc: add jumbo frames support for ENETC v4

committed 02:41PM - 30 Apr 25 UTC

Confirmed with NETC IP team, with the default memory on i.MX95, there is no issu…e with supporting jumbo frames functionally. But if the use-case requires jumbo frames and small size frames on all ports, running at line-rates, there might be performance issues. But this is corner case, we should not drop support for jumbo frames because of this, and some customers have jumbo frames requirement in DPDK. So add the support for jumbo frames to ENETC v4.

Is there a timeline for a Torizon release with this 6.12 kernel? Am I better off pulling in this patch in a custom build?
