The following configs are set to 'm' to make x86 the same
as aarch64.
  CONFIG_NET_EMATCH_CMP=m
  CONFIG_NET_EMATCH_NBYTE=m
  CONFIG_NET_EMATCH_U32=m
  CONFIG_NET_EMATCH_META=m

Some commonly used cases need CONFIG_NET_EMATCH_CMP,
for example:

tc qdisc add dev eth0 root handle 1: prio bands 4
tc qdisc add dev eth0 parent 1:4 handle 40: netem delay 20ms 2ms
tc filter add dev eth0 parent 1: protocol ip prio 4 basic match

Aligned NET_SCHED configs with aarch64, except:

1. CONFIG_NET_SCH_ATM is not enabled since we don't use
   ATM on cloud, and CONFIG_ATM is not enabled
2. CONFIG_NET_SCH_DEFAULT is not set since we still use
   pfifo_fast as the default scheduler.
3. CONFIG_NET_SCH_FQ_CODEL set to 'm' since we don't use
   fq_codel as the default qdisc
