Hi,
I try to use the WMM/WME system with the dirver madwifi-ng but I've some
problems. I saw the doc [NTR-UM-feb-2006-1][Hayoung]WMM.pdf.
I've two PC with the same wifi card (Cisco Aironet CB21AG PCMCIA), one
in ap mode and the other in sta mode. I made a bridge between the pcmcia
wifi card and the ethernet card on both pc.=20
My test is to send packet on the ethernet card on one pc and see what go
out at the other ethernet card of the other pc. And would like to see
how to work the QoS.
When I use the flag TOS or DSCP it works (not clearly but it works) but
when I use the Vlan Tag, there isn't priority in the different flow.
I reead the code in the file ieee80211_output.c and I saw that :
97 if (ni->ni_vlan !=3D 0 && vlan_tx_tag_present(skb)) {
98 u_int32_t tag=3D0;
99 int v_pri;
100 =09
101 if (vap->iv_vlgrp =3D=3D NULL) {
102 IEEE80211_NODE_STAT(ni, tx_novlantag);
103 ni->ni_stats.ns_tx_novlantag++;
104 return 1;
105 }
106 if (((tag =3D vlan_tx_tag_get(skb)) &VLAN_VID_MASK) =
!=3D
107 (ni->ni_vlan & VLAN_VID_MASK)) {
108 IEEE80211_NODE_STAT(ni,tx_vlanmismatch);
109 ni->ni_stats.ns_tx_vlanmismatch++;
110 return 1;
111 }
112 if (ni->ni_flags & IEEE80211_NODE_QOS) {
113 v_pri =3D (tag >> VLAN_PRI_SHIFT) =
&VLAN_PRI_MASK;
114 switch (v_pri) {
115 case 1:
116 case 2: /* Background (BK) */
117 v_wme_ac =3D WME_AC_BK;
118 break;
119 case 0:
120 case 3: /* Best Effort (BE) */
121 v_wme_ac =3D WME_AC_BE;
122 break;
123 case 4:
124 case 5: /* Video (VI) */
125 v_wme_ac =3D WME_AC_VI;
126 break;
127 case 6:
128 case 7: /* Voice (VO) */
129 v_wme_ac =3D WME_AC_VO;
130 break;
131 }
132 }
133 }
I don't understand why it doesn't work. I looked the variable
ni->ni_vlan, it is equal to zero. Why ? Is not finish to implement ??
Can you give me some tips for finish or develop this ???
