4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Arjun Vynipadath <arjun@xxxxxxxxxxx> [ Upstream commit d7cb44496a9bb458632cb3c18acb08949c210448 ] Setting sge_uld_rxq_info to NULL in free_queues_uld(). We are referencing sge_uld_rxq_info in cxgb_up(). This will fix a panic when interface is brought up after a ULDq creation failure.
