The driver didn't implement any advanced hardware features, so GSO was unsupported. Still, I've found the performance for this SoC is heavily limited by memory bandwith and implementing scatter/gather support and hw checksum offload improves TCP_STREAM performance greatly (About doubled throughput). Case in point, a second device with basically the same SoC, but slightly faster (384MHz instead of 320MHz) and double the memory bandwith (two chips instead of one) reaches twice the speed of the first device (and also doubles the speed when scatter/gather and checksum offload is enabled). I haven't done any further testing with fq_codel yet. -- Tobias PGP: http://8ef7ddba.uguu.de _______________________________________________ Codel mailing list [email protected] https://lists.bufferbloat.net/listinfo/codel
