Since the proper handling of CQE_RX_TRUNCATED type is important, could any
of you backport this patch to the stable branches: 5.16 & 5.15?

Only patches which are in Linus's tree can be backported to stable.
You sent this change for -next so no, it can't be backported now.
You need to wait until 5.17 final is released and then ask Greg KH 
to backport it.
