[lwip-users] DHCP: malloc within the rx isr

[Tom C. Barker]

Hello,

I'm finding that in a dhcp response, I get following 
procedure stack:

        RxIsr
        eth_input
        ip_input( pbuf*, netif* )
        udp_input( pbuf*, netif* )
        dhcp_recv
        dhcp_unfold_reply
        mem_malloc( unsigned long )
        sys_sem_wait()
        sysarch_timeouts()

This essentially leads to the possibility that the isr could
need to wait for resources in the malloc function.

Is there an implementation of dhcp using the api/mailboxes?
Or could someone suggest a way around this situation?

Tom
