Thread: Breaking out of a loop

I'm just confused to think of a simple method to do this but

Code:

while (1) {

          length = recvfrom(s, buffer, BUF_SIZE, 0, NULL, NULL);

           if (eh->h_proto == ETH_P_NULL && memcmp( (const void*)eh->h_dest, (const void*)src_mac, ETH_MAC_LEN) == 0 ) {
			/* Comparing the Ethertype*/
			if(memcmp((void*)(etherhead+14), FCoe,2) == 0 || memcmp((void*)(etherhead+14),FIP,2) == 0){
				Ethfrm->ptr = (struct FCfrm_t *)(&Ethfrm->pad);  // Ethfrm pointer 
			} else if(memcmp((void*)(etherhead+14), VLAN,2) == 0){
				Ethfrm->ptr = (struct FCfrm_t *)(&Ethfrm->reserved);
				printf("VLAN HEADER\n");
				if((etherhead[16]& 0x10) == 0x10){
					//printf("readint %02X \n",etherhead[16]);
					printEthfrm(Ethfrm);
					//break;
				}
			} else {
				printEthfrm(Ethfrm);
				//break;
			}
		
			/* Setting the FCframe_t StructureStart Pointer to the EthernetFrame*/
			Ethfrm->ptr->StructureStart = Ethfrm;
                       ....
			.....
			....
             }
}

Everytime i break i break out of the while loop but I want to break out of the if statement with the true arguement and I'm kinda not sure how to do it simply without just overdoing it.
