I agree, I find it difficult to read. I'm wondering, is it
necessary to have these nested if and else statements? Sorry
if it isn't terribly obvious at a glance since I'm writing this
while in class. Maybe something like the code snippet below
would be better.
if (sta && sta->vht_cap.vht_supported) {
tcb_desc->hw_rate =
- _rtl_get_vht_highest_n_rate(hw, sta);
+ _rtl_get_vht_highest_n_rate(hw, sta);
+ } else if (sta && sta->ht_cap.ht_supported) {
+ tcb_desc->hw_rate =
+ _rtl_get_highest_n_rate(hw, sta);
+ } else if (rtlmac->mode == WIRELESS_MODE_B) {
+ tcb_desc->hw_rate =
+ rtlpriv->cfg->maps[RTL_RC_CCK_RATE11M];
} else {
- if (sta && (sta->ht_cap.ht_supported)) {
- tcb_desc->hw_rate =
- _rtl_get_highest_n_rate(hw, sta);
- } else {
- if (rtlmac->mode == WIRELESS_MODE_B) {
- tcb_desc->hw_rate =
-
rtlpriv->cfg->maps[RTL_RC_CCK_RATE11M];
- } else {
- tcb_desc->hw_rate =
-
rtlpriv->cfg->maps[RTL_RC_OFDM_RATE54M];
- }
- }
+ tcb_desc_hw_rate =
+ rtlpriv->cfg->maps[RTL_RC_OFDM_RATE54M];
}
}
Thanks,
