In the Linux kernel, the following vulnerability has been resolved:

RDMA/irdma: Fix sleep from invalid context BUG

Taking the qos_mutex to process RoCEv2 QP's on netdev events causes a kernel splat.

Fix this by removing the handling for RoCEv2 in irdma_cm_teardown_connections that uses the mutex. This handling is only needed for iWARP to avoid having connections established while the link is down or having connections remain functional after the IP address is removed.

BUG: sleeping function called from invalid context at kernel/locking/mutex.
