+Subject: [PATCH] ixgbe: fix a build warning being treated as error
+
+Upstream-Status: Inappropriate [other]
+
+The change is part of a feature commit upstream (e0ba4e77605ab500518247cb6fab98dd3d87ba97)
+that we don't want to backport.
+
+Initialize the data byte to avoid warnings like:

+          uninitialized in this function [-Werror=maybe-uninitialized]
+          *data |= bit << i;
+                ^
