Guillaume Nault f8879e85f0 utils: bump max args number to 512 for batch files 
Large tc filters can have many arguments. For example the following
filter matches the first 7 MPLS LSEs, pops all of them, then updates
the Ethernet header and redirects the resulting packet to eth1.

filter add dev eth0 ingress handle 44 priority 100 \
  protocol mpls_uc flower mpls                     \
    lse depth 1 label 1040076 tc 4 bos 0 ttl 175   \
    lse depth 2 label 89648 tc 2 bos 0 ttl 9       \
    lse depth 3 label 63417 tc 5 bos 0 ttl 185     \
    lse depth 4 label 593135 tc 5 bos 0 ttl 67     \
    lse depth 5 label 857021 tc 0 bos 0 ttl 181    \
    lse depth 6 label 239239 tc 1 bos 0 ttl 254    \
    lse depth 7 label 30 tc 7 bos 1 ttl 237        \

  action vlan pop_eth pipe                         \
  action vlan push_eth                             \
    dst_mac 00:00:5e:00:53:7e                      \
    src_mac 00:00:5e:00:53:03 pipe                 \
  action mirred egress redirect dev eth1

This filter has 149 arguments, so it can't be used with tc -batch
which is limited to a 100.

Let's bump the limit to 512. That should leave a lot of room for big
batch commands.

v2:
   -Define the limit in utils.h (Stephen Hemminger)
   -Bump the limit even higher (256 -> 512) (Stephen Hemminger)
