Mechanically convert netmap(4) to DrvAPI

[vmaffione]

A first pass.

sys/dev/netmap/netmap.c

2259

if_name() or if_getdname() ?

2872

This is not ifnet stuff, so it should not be touched.

3976

Yep, we need a way to grab the if_input method. Can DRVAPI expose that?

sys/dev/netmap/netmap_freebsd.c

354–356

So a if_getinputfn() maybe?

389–390

What about a if_gettransmitfn()?

sys/dev/netmap/netmap_generic.c

110

You can ignore this, it is Linux specific.

sys/dev/netmap/netmap_mem2.c

2125

You can drop all of these. Not related to struct ifnet.

2143

Drop.

2155–2156

Drop.

2170

Drop.

2796

Drop

2804

Drop

Address feedback. Update with new IfAPI accessors.

[jhibbits]

Use the right diff...

This must be wrongly changed by tools ;)
Should be if_getcapenable(sc->ifp)

764

Is this removal intended ?

sys/dev/netmap/netmap.c

2259

if_name() or if_getdname() ?

I think this should be if_name().

sys/net/if.c

const char *    
if_name(if_t ifp)       
{                       
        return ((struct ifnet *)ifp)->if_xname;
}

2264

if_getdname(), is this intended ?

sys/dev/netmap/netmap_freebsd.c

621–629

@vmaffione
The mtu set got overwritten by line 626
if_setmtu(ifp, ETHERMTU);

sys/dev/netmap/netmap_kern.h

1723

Style(9).

2030

Small nits, align member np_ifp

sys/dev/netmap/netmap_vale.c

414

Must be wrongly changed by tools ;)

1387

@vmaffione
Is this intended, if_getdname() or if_name() ?

sys/dev/netmap/if_ptnet.c

And somehow this didn't get caught even in a LINT build. The script is rather naive, so I've had to do a lot of these fixes, caught by build failures.

764

Not at all.

sys/dev/netmap/netmap.c

2259

if_name() gets ifp->if_xname, so it's a literal conversion.

3976

Yeah, I'll need to add an accessor for it.

sys/dev/netmap/netmap_freebsd.c

354–356

Good enough a name as any.

[jhibbits]

Address feedback from @zlei.

[vmaffione]

Still some changes to be done.

sys/dev/netmap/if_ptnet.c

444

You have a typo here, since this is a multi line assignment

1877

Why the comment?

sys/dev/netmap/netmap.c

2264

This should be the interface name, so if_name looks good to me

2272

this should be if_name

2872

please drop the comment

sys/dev/netmap/netmap_freebsd.c

621–629

That's right, thanks. I dropped that line in the src main branch.

sys/dev/netmap/netmap_generic.c

1118

Please drop the comments.

sys/dev/netmap/netmap_mem2.c

2125

Please drop also the space added at the end of the lines.

2520

This should be if_name(ptif->ifp)

2560

This should be if_name(curr->ifp)

sys/dev/netmap/netmap_vale.c

1387

Yes, if_name is correct.

[jhibbits]

I don't know how any of the issues you pointed out compiled in the first place. No errors on them. Will post an updated diff shortly.

sys/dev/netmap/if_ptnet.c

444

No idea at all how this was not caught by the compiler; pretty embarassing.

1877

It shouldn't be there, thought I removed them all.

[vmaffione]

sys/dev/netmap/if_ptnet.c

444

no worries, it's just unsettling if not catched by a compiler :)

[jhibbits]

Address feedback. No more DRVAPI comments in the code.

[zlei]

Looks good to me.

sys/dev/netmap/netmap_mem2.c

2121

Drop spaces at the end of the lines.
