Subject: [PATCH v2 0/5] Rust abstractions for network device drivers

This patchset adds minimum Rust abstractions for network device
drivers and an example of a Rust network device driver, a simpler
version of drivers/net/dummy.c.

The major change is a way to drop an skb (1/5 patch); a driver needs
to explicitly call a function to drop a skb. The code to let a skb
go out of scope can't be compiled.

I dropped get_stats64 support patch that the current sample driver
doesn't use. Instead I added a patch to update the NETWORKING DRIVERS
entry in MAINTAINERS.

Changes since v1 [1]:
- a driver must explicitly call a function to drop a skb.
- simplify the code (thanks to Benno Lossin).
- update MAINTAINERS file.
