From 4abbd2e3c1db671fa1286390f1310aec78386f1d Mon Sep 17 00:00:00 2001 From: Dust Li Date: Thu, 12 Oct 2023 20:37:29 +0800 Subject: net/smc: return the right falback reason when prefix checks fail In the smc_listen_work(), if smc_listen_prfx_check() failed, the real reason: SMC_CLC_DECL_DIFFPREFIX was dropped, and SMC_CLC_DECL_NOSMCDEV was returned. Althrough this is also kind of SMC_CLC_DECL_NOSMCDEV, but return the real reason is much friendly for debugging.
