?Hello,
I use LWIP in professional capacity.
Here I face a common warning due ot a varialble defined in file viz. pbuf.c
When LWIP Asserts are off compilation warning is seen.
Please find attached a patch which helps get rid of this warning.
Please let me know if this can be pulled in man stream.
Thanks & Best Regards,
Nirav
