[SRU][Xenial][PATCH 0/1] s390/qeth: fix underestimated count of buffer elements

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1750810

== SRU Justification ==
Mainline commit 89271c65ed fixes the calculation of required buffer elements for skb.

Problem: skbs of certain lengths cause qeth to miscalculate the
              number of needed IO buffer elements, resulting in
              malformed TX buffer descriptors. When such a buffer is
              presented to the HW, it triggers a Subchannel Program
              Check. qeth handles this by starting device recovery.

Solution: Fix the buffer element calculation, so that qeth builds
              proper TX buffer descriptors.

== Fix ==
commit 89271c65edd599207dd982007900506283c90ae3

== Regression Potential ==
