that's the one part i'm unsure of and i'll have to look at. right
now, the BBB connects over the network via USB just fine, so all i
need to do is verify that that doesn't require any loadable modules.
on the BBB, i have this from /proc/config.gz:
CONFIG_USB_NET_RNDIS_HOST=m
CONFIG_USB_NET_RNDIS_WLAN=m
CONFIG_USB_ETH_RNDIS=y
CONFIG_USB_FUNCTIONFS_RNDIS=y
CONFIG_USB_G_MULTI_RNDIS=y
and from lsmod, the only apparently related module is "g_multi":
g_multi 55905 2
libcomposite 15228 1 g_multi
but i don't know anything about that module. so first guess is that
the kernel on the BBB might have everything it needs, unless someone
who knows way more about RNDIS than i do can spot a flaw.
will test all this shortly, thanks for your help.
