Thanks for the reply Tony…
For debug logs do you mean the “FSL debug console”? if yes, these are my logs currently:

about the pxInterface->pfInitialize, it returns in pxMyInterface.
From the debugger i can see the interface being populated:
pxMyInterface NetworkInterface_t * 0x2000608c <xInterfaces>
pcName const char * 0x20004f8c <pcName.4> "NXP10600
pvArgument void * 0x0
pfInitialise NetworkInterfaceInitialiseFunction_t 0x60002dad <prvNXP1060_NetworkInterfaceInitialise>
pfOutput NetworkInterfaceOutputFunction_t 0x60002f21 <prvNXP1060_NetworkInterfaceOutput>
pfGetPhyLinkStatus GetPhyLinkStatusFunction_t 0x60002fbd <prvNXP1060_GetPhyLinkStatus>
bits struct {...} {...}
pxEndPoint struct xNetworkEndPoint * 0x200060ac <xEndPoints>
pxNext struct xNetworkInterface * 0x0
and if i expand a little, it populates like this (JSON formatted for readability):

About the BOARD_InitENETPins i double checked it, but i was confident it was already ok because i used the default board.c|h files provided by NXP for the evaluation board.
The only thing i don’t understand is the “ENET_INT” pin, because in the LwIP example it is pulled up (set as output and HIGH) before PHY reset, and i can’t see any code that reconfigures it as input with interrupt; in my code i commented out this part (in the InitEthernet function) but i can see that it is configured as interrupt during pin config and it is pulled-up by 1k resistor.
Here is the relevant portion from LwIP example :
// main.c
int main(void)
{
gpio_pin_config_t gpio_config = {kGPIO_DigitalOutput, 0, kGPIO_NoIntmode};
BOARD_ConfigMPU();
BOARD_InitBootPins();
BOARD_InitBootClocks();
BOARD_InitDebugConsole();
BOARD_InitModuleClock();

GPIO_PinInit(GPIO1, 4, &gpio_config);
GPIO_PinInit(GPIO1, 22, &gpio_config);
/* Pull up the ENET_INT before RESET. */
GPIO_WritePinOutput(GPIO1, 22, 1);
GPIO_WritePinOutput(GPIO1, 4, 0);
SDK_DelayAtLeastUs(10000, CLOCK_GetFreq(kCLOCK_CpuClk));
GPIO_WritePinOutput(GPIO1, 4, 1);
MDIO_Init();
g_phy_resource.read = MDIO_Read;
g_phy_resource.write = MDIO_Write;
/* Initialize lwIP from thread */
if (sys_thread_new("main", stack_init, NULL, INIT_THREAD_STACKSIZE, INIT_THREAD_PRIO) == NULL)
LWIP_ASSERT("main(): Task creation failed.", 0);
vTaskStartScheduler();
/* Will not get here unless a task calls vTaskEndScheduler ()*/
return 0;
