Thank you for your contribution, it has been applied to my local
review-ilpo-fixes branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-fixes branch only once I've pushed my
local branch there, which might take a while.

The list of commits applied:
[1/1] platform/mellanox: mlxbf-tmfifo: fix vring_desc.len assignment
      commit: 109f4d29dade8ae5b4ac6325af9d1bc24b4230f8
