From cbfe31b5d74dcfba46329813855e28e53d080d57 Mon Sep 17 00:00:00 2001 From: Pawel Kaminski Date: Thu, 25 Jul 2019 01:55:40 -0700 Subject: [PATCH] ice: Change type for queue counts These queue variables are being assigned values that are type u16. Change the local variables to match these types. Since these represent queue counts, they should never be negative.
