windows - How to real time convert Ethernet packet to Wireless packet? -

-

in case of ethernet header have destination mac address , source mac address.

in case of 802.11 packets there @ minimum 3 mac addresses , in cases 4 mac addresses.

how 802.11 packet formed using 802.3 packet? know native wifi doing conversion in case windows. want know how achieving?

"how 802.11 packet formed using 802.3 packet?"

the conversion (between 802.3 , 802.11 mac frames) happens @ link layer. implementation details platform , driver-dependent.

an example of how these done in linux kernel (using soft-mac 802.11 driver):
