just for reference purposes. This commit includes 1.4 -> 1.4.1 sync for kame branch. The branch does not compile at all (due to the lack of ALTQ and some other source code). Please do not try to modify the branch, this is just for referenre purposes. synchronization to latest KAME will take place on HEAD branch soon.

* - foo_control
|
|
* NetBSD, FreeBSD 3
|
|
* needs to give struct proc * as argument
|
|
* OpenBSD, BSDI [34], FreeBSD 2
|
|
* do not need struct proc *
|
|
* - bpf:
|
|
* OpenBSD, NetBSD, BSDI [34]
|
|
* need caddr_t * (= if_bpf **) and struct ifnet *
|
|
* FreeBSD 2, FreeBSD 3
|
|
* need only struct ifnet * as argument
|
|
* - struct ifnet
|
|
* use queue.h? member names if name
|
|
* --- --- ---
|
|
* FreeBSD 2 no old standard if_name+unit
|
|
* FreeBSD 3 yes strange if_name+unit
|
|
* OpenBSD yes standard if_xname
|
|
* NetBSD yes standard if_xname
|
|
* BSDI [34] no old standard if_name+unit
|
|
* - usrreq
|
|
* NetBSD, OpenBSD, BSDI [34], FreeBSD 2
|
|
* single function with PRU_xx, arguments are mbuf
|
|
* FreeBSD 3
|
|
* separates functions, non-mbuf arguments
|
|
* - {set,get}sockopt
|
|
* NetBSD, OpenBSD, BSDI [34], FreeBSD 2
|
|
* manipulation based on mbuf
|
|
* FreeBSD 3
|
|
* non-mbuf manipulation using sooptcopy{in,out}()
|
|
* - timeout() and untimeout()
|
|
* NetBSD, OpenBSD, BSDI [34], FreeBSD 2
|
|
* timeout() is a void function
|
|
* FreeBSD 3
|
|
* timeout() is non-void, must keep returned value for untimeuot()
|
|
* - sysctl
|
|
* NetBSD, OpenBSD
|
|
* foo_sysctl()
|
|
* BSDI [34]
|
|
* foo_sysctl() but with different style
|
|
* FreeBSD 2, FreeBSD 3
|
|
* linker hack
|
|
*
|
|
* - if_ioctl
|
|
* NetBSD, FreeBSD 3, BSDI [34]
|
|
* 2nd argument is u_long cmd
|
|
* FreeBSD 2
|
|
* 2nd argument is int cmd
|
|
* - if attach routines
|
|
* NetBSD
|
|
* void xxattach(int);
|
|
* FreeBSD 2, FreeBSD 3
|
|
* void xxattach(void *);
|
|
* PSEUDO_SET(xxattach, if_xx);
|
|
*
|
|
* - ovbcopy()
|
|
* in NetBSD 1.4 or later, ovbcopy() is not supplied in the kernel.
|
|
* bcopy() is safe against overwrites.
|
|
* - splnet()
|
|
* NetBSD 1.4 or later requires splsoftnet().
|
|
* other operating systems use splnet().
|
|
*
|
|
* - dtom()
|
|
* NEVER USE IT!
|
|
*
|
|
* - struct ifnet for loopback interface
|
|
* BSDI3: struct ifnet loif;
|
|
* BSDI4: struct ifnet *loifp;
|
|
* NetBSD, OpenBSD, FreeBSD2: struct ifnet loif[NLOOP];
|
|
*
|
|
* odd thing is that many of them refers loif as ifnet *loif,
|
|
* not loif[NLOOP], from outside of if_loop.c.
