Sure, so create a new directory in src/lib for libbozohttpd, get the library to build with a new Makefile and set LIBISPRIVATE? Sevan

Re: CVS commit: src/sys/dev/pci/ixgbe
Hi,
I am now seeing that packet reception stops. tcpdump will only show
outgoing packets and no incoming packets.
ifconfig ixgX down
ifconfig ixgX up
gets things going again.
Code from 2018-02-24 was fine and I think even code shortly before this
commit was fine, but there was the mbuf used-after-free issue that hit
me pretty hard. So the system wasn't running for too long anyway.
Does that ring a bell ?

src/sys/dev/pci/ixgbe: ix_txrx.c ixgbe.h ixgbe_netbsd.c ixgbe_netbsd.h
ixgbe_osdep.h
Log Message:
Don't free and reallocate bus_dmamem when it's not required. Currently,
the watchdog timer is completely broken and never fire (it's from FreeBSD
(pre iflib)). If the problem is fixed and watchdog fired, ixgbe_init() always
calls ixgbe_jcl_reinit() and it causes panic. The reason is that
ixgbe_local_timer1(it includes watchdog function) is softint and
xgbe_jcl_reinit() calls bus_dmamem*() functions. bus_dmamem*() can't be called
from interrupt context.
One of the way to prevent panic is use worqueue for the timer, but it's
not a small change. (I'll do it in future).
Another way is not reallocate dmamem if it's not required. If both the MTU
(rx_mbuf_sz in reality) and the number of RX descriptors are not changed, it's
not required to call bus_dmamem_{unmap,free}(). Even if we use workque, this
change save time of ixgbe_init().
I have a code to fix broken watchdog timer but it sometime causes watchdog
timeout, so I don't commit it yet.
