Hi all, I`ve started working on a new project were a high performace hdlc channel is needed (at least 4Mbps on MPC8xx-50Mhz). I found several drivers for hdlc, but some are not very fast (copies memory,... ), most of them calls netif_rx from inside interrupt_handler (I don`t think this is the best place for doing that, watchdog may expire if the interface gets very busy..). The only driver I found that seems to be really fast and doesnt do all this stuff in interrupt context is for kernel-2.2 (QSLINUX). Does anyone ported this to 2.4 or knows another implementation of hdlc driver that could do this the way I`m thinking?
