From 313ed2d52052ad8dab9a6182cde55a832873cbea Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Thu, 27 Aug 2015 11:42:31 -0400 Subject: [PATCH] i40evf: propagate interrupt allocation failure Lower level functions are properly reporting errors, and higher-level functions are correctly responding to errors, but the errors aren't actually getting through. Typically, the middle-manager function seems to want to shield its boss from any bad news. This change fixes a panic if the driver is unable to enable MSI-X or is unable to acquire enough vectors.
