Fixing wrong setting of partition enforcement bits on switch ports.
When an HCA port is configured with a certain pkey, the peer port
on the switch should turn on outbound partition enforcement bit only.
Turning on the inbound enforcement will cause the switch to drop
valid packets if the HCA is partial member.
Nice catch!
Interesting how "inbound enforcement" switch service could be useful at
all?
It appears that the inbound enforcement is actually a useful thing.
Basically, it all boils down to the question where would you drop
the packet with a wrong pkey.
With only outbound enforcement the packet is dropped by the
*last* port before target. With inbound the packet is dropped
by the *first* port - the one that is connected to the source HCA.
Anyway, I'm reviewing the spec again in this area, and I'll probably
post a patch that turns on the inbound enforcement too later today.
