+Subject: [PATCH] igc: enable HW vlan tag insertion/stripping by default
+
+This is enabled by default in other Intel drivers I've checked (e1000, e1000e,
+iavf, igb and ice). Fixes an out-of-the-box performance issue when running
+OpenWrt on typical mini-PCs with igc-supported Ethernet controllers and 802.1Q
+VLAN configurations, as ethtool isn't part of the default packages and sane
+defaults are expected.
+
+In my specific case, with an Intel N100-based machine with four I226-V Ethernet
+controllers, my upload performance increased from under 30 Mb/s to the expected
+~1 Gb/s.
