It seems you are doing something wrong. The QP is allocated when the
interface is created and remains the same when the interface is
brought up and down:
# ip addr show dev ib0
7: ib0: <BROADCAST,MULTICAST,UP> mtu 2044 qdisc pfifo_fast qlen 128
link/[32] 00:02:04:04:fe:80:00:00:00:00:00:00:00:05:ad:00:00:01:82:06
brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff
# ifconfig ib0 down
# ifconfig ib0 up
# ip addr show dev ib0
7: ib0: <BROADCAST,MULTICAST,UP> mtu 2044 qdisc pfifo_fast qlen 128
link/[32] 00:02:04:04:fe:80:00:00:00:00:00:00:00:05:ad:00:00:01:82:06
