 I am USING BOTH ETHERNET+USB IN STM32H743ZI  WHEN I CONNECT ETHERNET THEN NORMAL BUFFER UPDATE PROBLEM OCCURING 

 
cnt_10=11;                                                      ///this buffer is updated     
MX_LWIP_Init(); //ETHERNET
HAL_Delay(10);
cnt_10=12;                                                      //this buffer is not updated
 
 
cnt_10=11;                                                     ///this buffer is updated                                            
buffer is updated but after calling MX LWIP Init(); then cnt_10=12 not updated why ?? inside calling mx_lwip_init();
 
 
after calling mx_lwip_init();
 
cnt_10=15;                                                 //this buffer is updated
netif_add(&gnetif, &ipaddr, &netmask, &gw, NULL, &ethernetif_init, &ethernet_input);
cnt_10=12;                                                 //this buffer is not updated
 
above netif_add(&gnetif, &ipaddr, &netmask, &gw, NULL, &ethernetif_init, &ethernet_input); i used cnt_10=15 buffer updated but after below  this  cnt_10=12 buffer not updated why??? give me proper solution.
