There was a problem with source address selection for ARP retransmissions, when an ARP entry was already pending. In such case, the `entry` value passed to `arp_prepare()` is NULL, which in result caused the `current_ip` variable being used as the source value. The problem with this approach is, that the `current_ip` is only set in IPv4 autoconf, the Ethernet L2 does not set this variable. In result, every retransmission of an ARP packet was sent with unspecified source address, preventing the response from being handled. Fix this by partially restoring the behaviour of the ARP source address assignment from before IPv4 autoconf was introduced. If the ARP is sent by the IPv4 autoconf, use the `current_ip` value provided. If entry is not set, use the source IPv4 address set in the actual data packet. Otherwise, search for a source address on the interface corresponding to the `entry`. Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no> |
