Subject: [0/6] ti cpsw driver port from freebsd for am335x
I add cpsw driver from freebsd and modify some code for my board, my board is
not beagleblack, so i am not sure it can work fine in BB board,to reduce phy
find process, I set phy address 4 and 6 for which phy address on my board,my
board has two eth port ,I set dualmac when attach;
can somebody test it on beaglebone and merge to beaglebone bsp?_______________________________________________
