Quickly browsing, I don't find "va" nor 0x2c in this RFC above? Could
you refer to page?

This RFC refers to replacing CS1 by LE

   o  This update to RFC 4594 removes the following entry from its
      Figure 4:

   |---------------+------+-------------------+---------+--------+----|
   | Low-Priority  | CS1  | Not applicable    | RFC3662 |  Rate  | Yes|
   |     Data      |      |                   |         |        |    |
    ------------------------------------------------------------------

      and replaces it with the following entry:

   |---------------+------+-------------------+----------+--------+----|
   | Low-Priority  | LE   | Not applicable    | RFC 8622 |  Rate  | Yes|
   |     Data      |      |                   |          |        |    |
    -------------------------------------------------------------------


static const struct symbol_table dscp_type_tbl = {
        .base           = BASE_HEXADECIMAL,
        .symbols        = {
                [...]
                SYMBOL("cs1",   0x08),
                [...]
                SYMBOL("le",    0x01),

Aliasing is fine, let's just clarify this first.

Thanks.
