* In order to reduce use of M_EXT outside of the mbuf allocator andRobert Watson2015-01-061-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | socket-buffer implementations, introduce a return value for MCLGET() (and m_cljget() that underlies it) to allow the caller to avoid testing M_EXT itself. Update all callers to use the return value. With this change, very few network device drivers remain aware of M_EXT; the primary exceptions lie in mbuf-chain pretty printers for debugging, and in a few cases, custom mbuf and cluster allocation implementations. NB: This is a difficult-to-test change as it touches many drivers for which I don't have physical devices. Instead we've gone for intensive review, but further post-commit review would definitely be appreciated to spot errors where changes could not easily be made mechanically, but were largely mechanical in nature.

It is believed that the extra destroy of the map was generally harmless since bus_dmamem_alloc() often uses special maps for which bus_dmamap_destroy() is a no-op (e.g. on x86).

* First real attempt at proper locking. The locking is a little complicatedDoug Ambrisko2008-01-181-121/+248
| | | | | | | | | | | | | | | | | | | | | | | since the the command and data that is being built to be sent to or read from the HW lives in the softc. Commands are later run via an_setdef etc. In the ioctl path various references are kept to the data stored in the softc so it needs to be protected. Almost think of the command in the softc a global variable since it essentially is. Since locking wasn't done in this type of context the commands would get corrupted. Thanks to avatar@ for catching some lock issues and dhw@ for testing. Things are a lot more stable except for the MPI-350 cards. My an(4) remote laptop stays on the network now. The driver should be changed so that it uses private memory that is passed to the functions that talk to the card. Then only those functions would really need to grab locks.

| | | | | | | | | | | | | | | | | | | | | | | 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.
