backports: adjust flow_dissector.patch
We copy over the net/core/flow_dissector.c code from
the kernel through the backports Kconfig magic for
our backport of NET_SCH_FQ_CODE:
config BACKPORT_USERSEL_NET_SCH_FQ_CODEL
tristate "Fair Queue Controlled Delay AQM (FQ_CODEL)"
depends on m
depends on !BACKPORT_KERNEL_2_6_25
default m if NET_SCH_FQ_CODEL=n
default m if BACKPORT_USERSEL_BUILD_ALL
#module-name sch_fq_codel
#c-file net/sched/sch_fq_codel.c
#c-file net/core/flow_dissector.c
This pulls net/core/flow_dissector.c into the backports
module as compat/net-core-flow_dissector.c. We don't need
all the code there. Patches under patches/backport-adjustments/
can be used to adjust that type of code. Some changes have
been made to code we delete which means we need to manually
adjust the patch we carry. This is a hint as one area we could
look to enhance better to do more automatic backport work.
