Can someone tell what kind of frames these are?

I built a simple sniffing program in C that gives me the raw frame data of all frames my monitor interface catches. Here is the code for it but I think it works fine.

#include <asm-generic/socket.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <fcntl.h> #include <errno.h> #include <sys/ioctl.h> #include <arpa/inet.h> #include <netinet/ether.h> #include <sys/socket.h> #include <netinet/in.h> #include <linux/if.h> #include <netdb.h> #include <linux/sockios.h> #define BYTE_TO_BINARY_PATTERN "%c%c%c%c%c%c%c%c" #define BYTE_TO_BINARY(byte) \ (byte & 0x80 ? '1' : '0'), \ (byte & 0x40 ? '1' : '0'), \ (byte & 0x20 ? '1' : '0'), \ (byte & 0x10 ? '1' : '0'), \ (byte & 0x08 ? '1' : '0'), \ (byte & 0x04 ? '1' : '0'), \ (byte & 0x02 ? '1' : '0'), \ (byte & 0x01 ? '1' : '0') void write_log(unsigned char *data, int size, int log_file){ for(int i = 0; i < size; i++){ if(i % 16 == 0 && i != 0){ dprintf(log_file, "\n"); } dprintf(log_file, "0x%02X ", data[i]); } dprintf(log_file, "\n"); for(int i = 0; i < size; i++){ if(i % 16 == 0 && i != 0){ dprintf(log_file, "\n"); } dprintf(log_file, BYTE_TO_BINARY_PATTERN" ", BYTE_TO_BINARY(data[i])); } dprintf(log_file, "\n\n\n"); } int main(int argc, char **argv){ int log_file = open("log.txt", O_CREAT | O_RDWR, S_IRWXO); int sock_raw = socket(AF_PACKET, SOCK_RAW, htons(ETH_P_ALL)); setsockopt(sock_raw, SOL_SOCKET, SO_BINDTODEVICE, argv[1], strlen(argv[1])); unsigned char *buffer = (unsigned char *)malloc(65536); int data_size = 0; while(1){ data_size = recvfrom(sock_raw, buffer, 65536, 0, 0, 0); write_log(buffer, data_size, log_file); } return 0; } 

Between many other frames that I think are fine I receive these which dont make any sense for me, neither in radiotap nor in 802.11 standard. Can someone tell what these are?

These are two frames and the binary for each one is the same as the hex.
