Quite unsurprisingly, thanks for coming back
Sorry for the noise. After more testing I've found out that the cause
was that I had BBR enabled on my laptop. Switching back to CUBIC fixed
the issue.
In other words, this patch is detrimental.

bgmac is used on Gigabit capable hardware, like Northstar and Northstar Plus,

The MIPS CPU runs at 300MHz on my unit.

On a linksys E1200v1 (actually a crossflashed E1000v2), the offloading features
give no measurable benefit to speed or latency. Furthermore, disabling GRO
actually improves iperf performance by a whoppimg 3mbps. Results:

Absolutely no driver disable
Ok fair enough. Will only disable GRO in the driver.
Tests were done using "ethtool -K eth0 gro off" and on.

Do you have a way to gene
On a linksys E1200v1 (actually a crossflashed E1000v2), the offloading features
give no measurable benefit to speed or latency. Furthermore, disabling GRO
actually improves iperf performance by a whoppimg 3mbps. Results:
