Shouldn't a sta include iv_ampdu_rxmax and iv_ampdu_density instead
when associating?

1) A driver initiates iv_ampdu_rxmax and iv_ampdu_density based on h/w
capabilities.

2) When a sta trying to associate,
ieee80211_send_mgmt()
{
        case IEEE80211_FC0_SUBTYPE_ASSOC_REQ:
            ieee80211_add_htcap();    /* the function in question */
}

3) When an ap receives the assoc_req packet, the ap will save ht
params to ni_htparam. Then the ap will use those values for Tx
packets.

4) The sta will receive packets which size is within the limits if the
sta included iv_ampdu_rxmax and iv_ampdu_density.
