definition of structure in C for 8139 lan card

[onus]

[http://lxr.free-electrons.com/source/drivers/net/8139too.c#L498][1]
On above link
What I am not getting is
the structure

static const struct {
            const char *name;
            u32 version; /* from RTL8139C/RTL8139D docs */
            u32 flags;
    } rtl_chip_info[] = {
            { "RTL-8139",
              HW_REVID(1, 0, 0, 0, 0, 0, 0),
              HasHltClk,
            },

gets expanded to

static const struct {
            const char *name;
            u32 version; /* from RTL8139C/RTL8139D docs */
            u32 flags;
    } rtl_chip_info[] = {
            { "RTL-8139",
    [B](b30, b29, b28, b27, b26, b23, b22)
            (b30<<30 | b29<<29 | b28<<28 | b27<<27 | b26<<26 | b23<<23 | b22<<22)
    (1, 0, 0, 0, 0, 0, 0),[/B]
              HasHltClk,
            },

I do not understand above type (2nd) of structure declaration.
