Figured I would poke someone to add this patch to the stable queue - I
don't see it in
https://patchwork.kernel.org/bundle/netdev/stable/?state=* right now.
This patch is reported to fix a severe upload speed regression in many
Intel wireless adapters existing since kernel 5.9, as described in
https://bugzilla.kernel.org/show_bug.cgi?id=209913

We're actually experimenting with letting Greg take networking patches
into stable like he does for every other tree. If the patch doesn't
appear in the next stable release please poke stable@ directly.

    iwlwifi: provide gso_type to GSO packets

    net/core/tso.c got recent support for USO, and this broke iwlfifi
    because the driver implemented a limited form of GSO.

    Providing ->gso_type allows for skb_is_gso_tcp() to provide
    a correct result.

    Fixes: 3d5b459ba0e3 ("net: tso: add UDP segmentation support")
