description |
Description: qeth: fix calculation of required buffer elements for skb
Symptom: Repeated device recovery due to Subchannel Program Checks
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.
Reproduction: Occurs for skbs where the last byte of the linear data
range / of a page frag sits on a page boundary.
Upstream Git Commit:
89271c65edd599207dd982007900506283c90ae3
kernel 4.16
backported to xenial/master-next
Here's a backport of the upstream commit for pre-4.8 kernels. |
