Toleration support for new IBM Z crypto hardware - Backport to focal (20.04)
Patch from kernel 5.14:
Summary: kernel: support new dynamic AP bus size limit
Description: This patch provides support for new dynamic AP bus message limit with the existing zcrypt device driver
and AP bus core code. There is support for a new
field 'ml' from the TAPQ query which indicates the
per card AP bus message size limit. This TAPQ improvement will come with an updated firmware and
this patch exploits this new field and thus makes
it possible to send/receive AP messages greater
than the current limit of 12K.
