'RELENG_4_7_0_RELEASE'.
This commit was manufactured to restore the state of the 4.7-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.
Add ${DEBUG_FLAGS} to CFLAGS in bsd.kmod.mk, not in scattered module2000-01-28T11:26:46ZBruce Evansbde@FreeBSD.org2000-01-28T11:26:46Zurn:sha1:9e4be63dd6e312fe0e864d23e9636f43cc869541

makefiles.
Get rid of some debugging cruft.2000-01-23T13:56:58ZNick Hibman_hibma@FreeBSD.org2000-01-23T13:56:58Zurn:sha1:0c4407576d8ec15f3caa6c0eda2ed3ff84d3bd37Attempt to fix a problem with receiving packets on USB ethernet interfaces.2000-01-10T23:12:54ZBill Paulwpaul@FreeBSD.org2000-01-10T23:12:54Zurn:sha1:a0067d7b89525cd8ed446d5e5c157514d043f74a
Packets are received inside USB bulk transfer callbacks, which run at
splusb() (actually splbio()). The packet input queues are meant to be
manipulated at splimp(). However the locking apparently breaks down under
certain circumstances and the input queues can get trampled.
There's a similar problem with if_ppp, which is driven by hardware/tty
interrupts from the serial driver, but which must also manipulate the
packet input queues at splimp(). The fix there is to use a netisr, and
that's the fix I used here. (I can hear you groaning back there. Hush up.)
The usb_ethersubr module maintains a single queue of its own. When a
packet is received in the USB callback routine, it's placed on this
queue with usb_ether_input(). This routine also schedules a soft net
interrupt with schednetisr(). The ISR routine then runs later, at
splnet, outside of the USB callback/interrupt context, and passes the
packet to ether_input(), hopefully in a safe manner.
The reason this is implemented as a separate module is that there are
a limited number of NETISRs that we can use, and snarfing one up for
each driver that needs it is wasteful (there will be three once I get
the CATC driver done). It also reduces code duplication to a certain
small extent. Unfortunately, it also needs to be linked in with the
usb.ko module in order for the USB ethernet drivers to share it.
Also removed some uneeded includes from if_aue.c and if_kue.c

bsd.kmod.mk. Cleaned up related things ($S and ${CLEANFILES}).

USB is loadable as a module as well.1999-11-22T03:46:33ZNick Hibman_hibma@FreeBSD.org1999-11-22T03:46:33Zurn:sha1:953dc38912e6267ecada137ed1e3c4d31c81e3b8
