From: David Bauer Date: Mon, 26 Oct 2020 20:59:47 +0000 (+0100) Subject: ipq40xx: enable RX hash / CTAG TX offloading for single-phy X-Git-Tag: v21.02.0-rc1~1222 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e73d866c6fc7dfad2fb7dd87345c90029bbda59d;p=openwrt%2Fstaging%2Fhauke.git ipq40xx: enable RX hash / CTAG TX offloading for single-phy This re-enables offloading features disabled by commit 9da2b567605b ("ipq40xx: fix ethernet vlan double tagging"). Single-PHY devices use port-based VLANs on the switch, therefore no S-TAG magic is involved here. Re-enabling these features restores throughput back to 950 Mbit/s.
