[PATCH 0/6] mcp251xfd: cleanups, optimize RTR, add len8_dlc and BQL support

[Marc Kleine-Budde <mkl@xxxxxxxxxxxxxx>]

Hello,

this is a series of 6 patches for the mcp251xfd driver. It first replaces an
open coded check for TX buffer space, optimizes RTR CAN frames, add len8_dlc
support and finally BQL support. As netdev_xmit_more() is quite complicated it
will be added in a later series.

regards,
Marc
