From e999ef15423b35473c0d94ff3dd2011a0f7ddb04 Mon Sep 17 00:00:00 2001 From: Justin Tee Date: Fri, 28 Jun 2024 10:20:04 -0700 Subject: scsi: lpfc: Cancel ELS WQE instead of issuing abort when SLI port is inactive During SLI port errata events, there should be no expectation that submitted outstanding WQEs will return back CQEs. In these situations, the driver should not rely on receiving CQEs from the SLI port to signal WQE resource clean up. Put an sli_flag LPFC_SLI_ACTIVE check in lpfc_els_flush_cmd() when walking the txcmplq. The sli_flag check helps determine whether to issue an abort or driver based cancel on outstanding WQEs. If !LPFC_SLI_ACTIVE, then there's no point to issue anything to the SLI port. Instead, let the driver based cancel logic clean up the submitted WQE resources. Also, enhance some abort log messages that help with future debugging.
