[lwip-users] NETIF_DEBUG vs NETIF_DEBUGF

Hi, I'm developing an application in Vitis 2022.2 that uses lwip211_v1_8 and targets a Zynq US MPSOC+. I turned on lwip_debug and I started getting an error telling me that NETIF_DEBUGF is not defined. I couldn't find NETIF_DEBUGF anywhere so I renamed NETIF_DEBUG in lwipopts.h to NETIF_DEBUGF.
