RDMA/rxe: Fix failure during driver load
[ Upstream commit 32a25f2ea690dfaace19f7a3a916f5d7e1ddafe8 ]
To avoid the following failure when trying to load the rdma_rxe module
while IPv6 is disabled, add a check for EAFNOSUPPORT and ignore the
failure, also delete the needless debug print from rxe_setup_udp_tunnel().
$ modprobe rdma_rxe
modprobe: ERROR: could not insert 'rdma_rxe': Operation not permitted
Fixes: dfdd6158ca2c ("IB/rxe: Fix kernel panic in udp_setup_tunnel")
