[lwip-devel] Upgrading from v1.3.0 to 1.4.0 - sys_now()

Hi,

I'm currently porting my Xilinx drivers from lwip 1.3.0 to 1.4.0 and have
found that the latest version now uses a sys_now() function which was not
used/needed previously.  Why is this now needed and what should the
frequency of the returned timestamp be (assuming it is just a 32-bit count
value)?

Thanks

Phil
