/* Ethernet common code */
Stop embedding struct ifnet at the top of driver softcs. Instead the struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.

- Consistently use if_printf() only in interface methods: if_start(), if_watchdog, etc., or in functions used only in these methods. In all other functions in the driver use device_printf(). - Use __func__ instead of typing function name. Submitted by: Alex Lyashkov <umka sevcity.net>

For the PC Card implementation of the CS8920M that's in my IBM EtherJet, the interrupt is selected in the eeprom based on the layout of the PC Card board. Since this is encoded into the EEPROM, and has no relationship to the IRQ that the pccard bridge routes the PC Card's interrupt pin to. As such, stop writing to that register. This gets my EtherJet working. # The eeprom reading code appears to be totally wrong for my EtherJet # card. This causes the card to bogusly detect the media options # available.

Minor clean up to shave about 1.5k off the size of the driver: o remove unused fields from softc and args from cs_alloc_irq o remove some commented code that will never be implemented. o Don't try to send a packet and see if it worked. We don't need this anymore, and it doesn't add any value. o tweaks for BNC and AUI. o limit possible time hung in the kernel to 4s rather than 40s.

Replace the if_name and if_unit members of struct ifnet with new members if_xname, if_dname, and if_dunit. if_xname is the name of the interface and if_dname/unit are the driver name and instance. This change paves the way for interface renaming and enhanced pseudo device creation and configuration symantics.
