* Replace local copy-and-paste implementations of printmbuf() in severalRobert Watson2014-09-101-17/+1
| | | | | | | | | | | | | | | | | | | | | device drivers with calls to the centralised m_print() implementation. While the formatting and output details differ a little, the content is essentially the same, and it is unlikely anyone has used this debugging output in some time. This change reduces awareness of mbuf cluster allocation (and, especially, the M_EXT flag) outside of the mbuf allocator, which will make it easier to refine the external storage mechanism without disrupting drivers in the future. Style bugs are preserved. Reviewed by: bz, glebius MFC after: 3 days Sponsored by: EMC / Isilon Storage Division Notes: svn path=/head/; revision=271373

Many remaining references to NET_.*_GIANT() and NET_CALLOUT_MPSAFE are still present in subsystems, and will be removed in followup commits.

Since we could get an interrupt after we free the ifp, and the interrupt handler depended on the ifp being still alive, this could, in theory, cause a crash. Eliminate this possibility by moving the if_free to after the bus_teardown_intr() call. Reason: bad previous commit. Would be restored by next commit. Notes: svn path=/head/; revision=150622

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-101-64/+74
| | | | | | | | | | | | | | | | | | | | | | | 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.
