Thales Fragoso 561708c34f Merge lookup and lookup_pure methods 2020-08-17 04:44:58 +00:00
Thales Fragoso 1e5de8d42c Only limit the neighbor cache rate after sending a request packet
Prior to this change, the neighbor cache would get limited even when the
device failed to process our arp packet, which could put the socket in
the waiting state in the next poll.

This change only limits the cache rate if the device successfully
consumed our packet.

Dario Nieuwenhuis 386f50dbd2 Assign map instead of using mem::replace.
This fixes build on latest nightly. The cause of the breakage
is this commit:

7c4ca59f4b

which added a #[must_use = "if you don't need the old value, you
can just assign the new value directly"] hint to mem::replace.

Ruben De Smet eebd8e431a Add ethernet feature-gate as default.
Disable ethernet-related features and framing based on a feature gate.

Add a no-ethernet option to Travis.

notes:
- allow(unused) is added when not using ethernet feature
- Don't run pretty-print doctest, ethernet is optional.

Andreas Molzer 8c3bdf907b Allow access to phy-device in ethernet
Adds accessor functions to the device implementing the phy::Device trait
within an ethernet interface. The intent is to allow access to read-only
methods such as gathering of device statistics or other diagnostics
while the interface is running. The interface does not hold any internal
invariants on the device, so that a mutable accessor can be added as
well.

Chris Branch 8ef6637b0b Implement Any-IP feature
Any-IP is the capability to accept packets locally even when the
destination address is not configured on any interface. This lets
a service bind to an entire subnet of addresses and is particularly
useful in anycast deployments.

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ab79ad14a2d51e95f0ac3cef7cd116a57089ba82

This feature is not available for IPv6 as it would be a nop: the current
IPv6 handler doesn't filter packets by the interface's IP address(es).
