I would really love to get something going out of this initiative: https://pointer.ngi.eu/pages/ngi-pointer-opencalls ... either with marvell wifi, 802.11ax, ath11k, mt76... gpon onts, just something, anything fq-ing at the very least, over fiber of any sort, would be a start. is there anyone out there with some spare time and needs some eu dollars? I tend to disagree that we need massive offloading on 802.11ax. We need firmware on the chip that does per station scheduling, for the rest of the queue management a smarter host cpu in the a72 class more than suffices, especially if the packets are arriving gso'd. > > -Toke > -- Make Music, Not War Dave T=C3=A4ht CTO, TekLibre, LLC http://www.teklibre.com Tel: 1-831-435-0729
