Update for arduino-esp32 v3.0

[webspiderteam]

I have done all update changes but I am getting these errors:
/appdata/local/arduino15/packages/esp32/tools/xtensa-esp32-elf-gcc/esp-12.2.0_20230208/bin/../lib/gcc/xtensa-esp32-elf/12.2.0/../../../../xtensa-esp32-elf/bin/ld.exe: /ESP32-ENC28J60.cpp:114: undefined reference to enc28j60_begin' /appdata/local/arduino15/packages/esp32/tools/xtensa-esp32-elf-gcc/esp-12.2.0_20230208/bin/../lib/gcc/xtensa-esp32-elf/12.2.0/../../../../xtensa-esp32-elf/bin/ld.exe: Documents\Arduino\ETH_ENC28J60/ESP32-ENC28J60.cpp:121: undefined reference to esp_eth_phy_new_enc28j60'

may be you can fix these issues. I not pro in C coding.

hi,

thanks for your PR 👍

I cloned your fork and got a totally different linker error (complaining about missing tcpipInit()), tried to solve that instead until I got a successful compilation, but I don't have an ENC28J60 to test with, I hope this will solve your linker error too.

I think there was an file encoding issue. Because I downloaded all files back and put them in workspace manually. Now all files shows there is changes but no difference.

Thanks for fixing Tcpipinit issue. I haven't testted with hardware yet but I don't think there will be an issue.
