Awhile ago I submitted this iproute2 patch: https://patchwork.ozlabs.org/patch/784165/
And the corresponding kernel patch: https://patchwork.ozlabs.org/patch/783696/ To allow the setting of arbitrary qdisc size table so that the packet scheduler code in __qdisc_calculate_pkt_len charges the correct bandwidth per my custom link layer. These patches were not applied because the reviewers didn't like that I added another enumeration to the kernel's UAPI: TC_LINKLAYER_CUSTOM. My question is: why is the setting of the STAB not exposed to userspace applications? This seems to be a powerful feature that is more generic than hard-coding the STABs for TC_LINKLAYER_ETHERNET and TC_LINK_LAYER_ATM. Or maybe I'm missing something and there is mechanism to do this without my iproute2 patch?
