0.7 build error

[jiayihu]

I've just updated to 0.7 but I cannot build anymore:

error[E0004]: non-exhaustive patterns: type `(&Cidr, &Cidr)` is non-empty
   --> /Users/jiayihu/.cargo/registry/src/github.com-1ecc6299db9ec823/smoltcp-0.7.0/src/wire/ip.rs:334:15

    |
    = help: ensure that all possible cases are being handled, possibly by adding wildcards or more match arms
    = note: the matched value is of type `(&Cidr, &Cidr)`

These are the enabled features:

smoltcp = { version = "0.7.0", default-features = false, features = ["socket-udp", "socket-icmp"]}

Rust version:

rustc 1.50.0-nightly (593fe977a 2020-11-20)

Yeah, when trying to use version 0.7 of the library I'm getting the following build errors:

Current features:
smoltcp = { version = "0.7", default-features = false, features = ["ethernet", "proto-ipv4"] }

@Dirbaio what should we do here, branch and release 0.7.1 with that fixed, or go straight to 0.8?

[Dirbaio]

I'll start a v0.7.x branch with all the non-breaking fixes. The NDISC one is also release-worthy.

[Dirbaio]

v0.7.1 is now out, with the fixes for feature combination issues!
