ARP

[Daven007]

I am just testing out SDK v2.10 which apparently overcomes a problems with ARP requests being ignored. However I am finding another issue with ARP in that the ESP seems to be sending out a couple of ARP requests with Tell 0.0.0.0 then a gratuitous ARP lke so:

No Time Source Destination port Protocol Length Info HW dest HW src
449 10:17:10.280026000 Espressi_a0:7e:57 Broadcast ARP 60 Who has 192.168.1.187? Tell 0.0.0.0 Broadcast Espressi_a0:7e:57
450 10:17:10.653304000 Espressi_a0:7e:57 Broadcast ARP 60 Who has 192.168.1.187? Tell 0.0.0.0 Broadcast Espressi_a0:7e:57
451 10:17:11.125178000 Espressi_a0:7e:57 Broadcast ARP 60 Gratuitous ARP for 192.168.1.187 (Request) Broadcast Espressi_a0:7e:57

This then seems to disrupt the TCP session which has to restart. Everything then recovers but why should this be happening?
