We found this new hardware, but unfortunately on the 3v1 hardware branch you can't ping a host on ether2 and ether3 with 65535 bytes packet size. Seems that everything you made using this branch is worse than ever and you only can ping lowering to 44600 bytes packet size. Anyone else can confirm that? Please, its a pain knowing such a hardware bug!

Ah, looks like you people couldn't correctly implement IP175D chip.. Oh my, all my 433AH UAH suddenly become 411AH since can't make better use of this chip! Also, note that IP175C is working great... I wonder why it was replaced... *sigh* Ive tested with most of all ROS versions up to 4.6
