Updated the git commit as follows and applied to
dpdk-next-net-eventdev/for-main. Thanks
event/octeontx: fix SSO fastpath
Segmentation fault is observed as soon as any application
with ethdev event is launched as ev->mbuf was not set properly.
Fixing sub event type violation as in OCTEONTX event device
sub_event_type is used to store the ethernet port identifier
when work is received from OCTEONTX ethernet device. This violates
the event device spec as sub_event_type should be 0 in the initial
receive stage. Setting sub_event_type to 0 after copying the port id
in single workslot mode.
Fixes: 44a2cebbd489 ("crypto/octeontx: add crypto adapter data path")
