>Description:
I am trying to build a kernel and its klm with ALTQ support.
I did build an amd64 kernel with the good options (cf how to repeat the problem for the exact configuration). The kernel is booting up but pfctl -f /etc/pf.conf reports :
# pfctl -f /etc/pf.conf
pfctl: igb0: driver does not support altq
I dug a bit in the driver code and found this written in the /usr/src/sys/modules/igb/Makefile :
# IGB_LEGACY_TX will override the stack if_transmit path and
# instead use the older if_start non-multiqueue capable interface.
# This might be desireable for testing, or to enable the use of
# ALTQ.
#CFLAGS += -DIGB_LEGACY_TX
I Did try to build the kernel with this CFLAG (at the make.conf level, then modifiying the Makefile just in case).
The build failed with this :
>How-To-Repeat:
Create a kernelconfig like this :
include GENERIC
ident COLORZ
options ALTQ
options ALTQ_CBQ # Class Based Queuing (CBQ)
options ALTQ_RED # Random Early Detection (RED)
options ALTQ_RIO # RED In/Out
options ALTQ_HFSC # Hierarchical Packet Scheduler (HFSC)
options ALTQ_PRIQ # Priority Queuing (PRIQ)
options ALTQ_NOPCC # Required for SMP build
and buildkernel gives :
# make -s -j5 buildkernel
[...]
/usr/src/sys/modules/igb/../../dev/e1000/if_igb.c:2383:19: error: unused variable 'txr' [-Werror,-Wunused-variable]
struct tx_ring *txr = adapter->tx_rings;
^
