Hi Andy,

I did the changes for the mbufs in the file /target/h/net/mbuf.h (Tornado 1.0.1)

e.g.:

old:     #define NUM_INIT_MBUFS    40
new:                                                       100        (initial number
of mbufs, increased if necessary)

old:    #define MAX_MBUFS            1500
new:                                                   3000        (in fact this is
the main point)

After recompiling the vxWorks image you have it. (/target/src/config/usrNetwork.c uses
this defined parameters)

I couldn't reconstruct your idea to change values in /target/h/netBufLib.h ???
We are using vxWorks 5.3.1 , Tornado 1.0.1.
