Subject: [PATCH net-next 0/13] pull-request: can-next 2022-03-13

Hello Jakub, hello David,

this is a pull request of 13 patches for net-next/master.

The 1st patch is by me and fixes the freeing of a skb in the vxcan
driver (initially added in this net-next window).

The remaining 12 patches are also by me and target the mcp251xfd
driver. The first patch fixes a printf modifier (initially added in
this net-next window). The remaining patches add ethtool based ring
and RX/TX IRQ coalescing support to the driver.

regards,
Marc
