Comment (by kallisti5):
Here are the results of my initial research:
Data was found by examining the calls to bus_setup_intr in each network
driver and looking for two factors:
* NULL in the 4th argument
* the INTR_FAST flag passed to the 3rd argument
Based on function here:
http://cgit.haiku-
os.org/haiku/tree/src/libs/compat/freebsd_network/bus.c#n343
'''Legacy interrupts:'''
* 3com
* broadcom440x
* dec21xxx
* ipro100
* marvell_yukon
* rtl8139
* syskonnect
* via_rhine

* wlan/wavelanwifi
* wlan/marvell88w8363
* wlan/ralinkwifi
* wlan/iprowifi4965
* wlan/iprowifi2200
'''Not legacy interrupts:'''
* ar81xx
* atheros813x
* attansic_l1
* attansic_l2
* jmicron2x0
* nforce
* wlan/marvell88w8335
'''Could be either:'''
* broadcom570x
* if (BGE_IS_5755_PLUS(sc) && sc->bge_flags & BGE_FLAG_MSI)? '''Not
legacy'''
* else? '''Legacy'''
* ipro1000
