Description

When creating an aggregate with 5 e1000g interfaces, the aggregate gets created, but a dladm show-link will only show the first 4.
Steps to reproduce:

root@danstore3:~# dladm create-aggr -l e1000g1 -l e1000g2 -l e1000g3 -l e1000g4 -l e1000g5 aggr1
root@danstore3:~# dladm show-link aggr1
LINK        CLASS     MTU    STATE    BRIDGE     OVER
aggr1       aggr      1500   up       --         e1000g1 e1000g2 e1000g3 e1000g4
root@danstore3:~# grep aggr1 /etc/dladm/datalink.conf 
aggr1   class=int,4;media=int,4;key=int,0;nports=int,5;portnames=string,e1000g1:e1000g2:e1000g3:e1000g4:e1000g5:;policy=int,4;fix_macaddr=boolean,0;force=boolean,0;lacp_mode=int,0;lacp_timer=int,1;

While looking for the solution, I found out that the same limit applies to printing the BRIDGE field.

I guess, it's a feature :-)

/*
 * structures for 'dladm show-link'
 */
static const ofmt_field_t link_fields[] = {
/* name,    field width,    index,    callback */
{ "LINK",    12,
    offsetof(link_fields_buf_t, link_name), print_default_cb},
{ "CLASS",    10,
    offsetof(link_fields_buf_t, link_class), print_default_cb},

    offsetof(link_fields_buf_t, link_state), print_default_cb},

    offsetof(link_fields_buf_t, link_bridge), print_default_cb},
