2016-01-27Convert rman to use rman_res_t instead of u_longJustin Hibbits
Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long. This is step one in migrating rman to use uintmax_t for resources instead of u_long. Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API. This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.

2015-01-06In order to reduce use of M_EXT outside of the mbuf allocator andRobert Watson
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.

Approved by: re (blanket) Notes: svn path=/head/; revision=147304
2005-06-10Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis
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.
