Re: [lwip-users] Struct packing/alignment problems

Hello,

etharp.c has this piece of code where the address of
the source IP address in the ARP header is passed
to the DHCP client:

if (for_us) dhcp_arp_reply(netif, &hdr->sipaddr);

The DHCP client will probably crash as it is not
fixed for the 32-bit case yet, in case this address
is not 32-bit aligned.

I would rather work with a local fix in etharp.c here
by a temporary variable solution instead of having the
fix spread over the lwIP code.

Leon.
