* Add new tunable 'net.link.ifqmaxlen' to set default send interfacesobomax2010-05-031-1/+1

Also add read-only sysctl with the same name, so that it's possible to retrieve the current value. MFC after: 1 month

* Make sbni(4) MPSAFE:jhb2008-07-044-124/+205
| | | | | | | | | | | | | | | | | | | | - Add a mutex to the softc and use it to protect the softc and device hardware. - Setup interrupt handler after attaching device to network stack. - Use device_set_desc() rather than device_quiet() plus a manual printf that simulates the normal probe printf. - Axe next_sbni_unit and instead just leave room for two sbni devices for each bus attachment. - Don't bzero the already-zero'd softc. - Add a detach method to the PCI driver. - Add a lock to protect the list of available devices used to chain interrupt handlers for dual port ISA cards. - Remove unused watchdog routine. - If if_alloc() fails, make sbni_attach() return an error rather than panic'ing. - Consolidate code to free bus resources into sbni_release_resources(). - Clear IFF_DRV_RUNNING|OACTIVE in stop() routine instead of in callers. - Let ether_ioctl() handle SIOCSIFMTU.

* - Store pointer to the link-level address right in "struct ifnet"ru2005-11-111-3/+3
| | | | | | | | | | rather than in ifindex_table[]; all (except one) accesses are through ifp anyway. IF_LLADDR() works faster, and all (except one) ifaddr_byindex() users were converted to use ifp->if_addr. - Stop storing a (pointer to) Ethernet address in "struct arpcom", and drop the IFP2ENADDR() macro; all users have been converted to use IF_LLADDR() instead.
* Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE andrwatson2005-08-091-9/+9
| | | | | | | | | | | | | | IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to ifnet.if_drv_flags. Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags. This helps prevent races between the network stack and device driver in maintaining the interface flags field. Many __FreeBSD__ and __FreeBSD_version checks maintained and continued; some less so.

* Stop embedding struct ifnet at the top of driver softcs. Instead thebrooks2005-06-103-25/+29
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | if the link-level address has been initialized already. The majority of modern drivers never does this and works fine, which makes me think that the check is totally unnecessary and a residue of cut&paste from other drivers. This change is done to simplify locking because now almost none of the drivers uses this field. The exceptions are "ct" "ctau" and "cx" where i am not sure if i can remove that part.

| | | | | | | | | | | | general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.
