Hi Larry :) Im afraid I didnt receive your answer to my last email.. in
case you sent, please resend, thanks :)
As for "dissecting" the issue, as you suggested, I have been filling
your code with debug lines.
Very interesting in my opinion is the report from
drivers/net/wireless/rtl818x/rtl8187/dev.c#rtl8187_configure_filter(),
as follows:
IN>changed_flags=240,total_flags=2147483888,multicast=0,priv->rx_conf=2425682954
>FIF_CONTROL
>FIF_OTHER_BSS
>not FIF_ALLMULTI
drivers/net/wireless/rtl818x/rtl8187/dev.c#rtl818x_iowrite32_async
drivers/net/wireless/rtl818x/rtl8187/dev.c#rtl8187_iowrite_async
OUT>total_flags=96,priv->rx_conf=2426207243
.. after, some daemon calls it again multiple times, but result is
always the same as follows:
IN>changed_flags=144,total_flags=2147483888,multicast=0,priv->rx_conf=2426207243
>not FIF_ALLMULTI
drivers/net/wireless/rtl818x/rtl8187/dev.c#rtl818x_iowrite32_async
drivers/net/wireless/rtl818x/rtl8187/dev.c#rtl8187_iowrite_async
net/mac80211/util.c#ieee80211_queue_work
OUT>total_flags=96,priv->rx_conf=2426207243
.. seeing anything unusual?
I have the strange feeling that "IN" value of priv->rx_conf could be
bugged.. as result the relative OUT value is maybe wrong.. :P
Anyway, could you please perform the same test on your working
interfaces, and report me the output?
The values of IN/OUT and so on, of rtl8187_configure_filter(), *AFTER*
calling "airmon-ng start wlan0"?
>From your probe, my interface type is as follow:
- "RTL8187vB (default)"
- PCI_EEPROM_WIDTH_93C46
- customer id 0
Please insert the following debug lines, as I did:
static void rtl8187_configure_filter()
{
printk(KERN_WARNING
"drivers/net/wireless/rtl818x/rtl8187/dev.c#rtl8187_configure_filter");
struct rtl8187_priv *priv = dev->priv;
printk(KERN_WARNING
"IN>changed_flags=%u,total_flags=%u,multicast=%llu,priv->rx_conf=%u",changed_flags,*total_flags,multicast,priv->rx_conf);
if (changed_flags & FIF_FCSFAIL) {
priv->rx_conf ^= RTL818X_RX_CONF_FCS;
printk(KERN_WARNING ">FIF_FCSFAIL");}
if (changed_flags & FIF_CONTROL) {
priv->rx_conf ^= RTL818X_RX_CONF_CTRL;
printk(KERN_WARNING ">FIF_CONTROL");}
if (changed_flags & FIF_OTHER_BSS) {
priv->rx_conf ^= RTL818X_RX_CONF_MONITOR;
printk(KERN_WARNING ">FIF_OTHER_BSS");}
if (*total_flags & FIF_ALLMULTI || multicast > 0) {
priv->rx_conf |= RTL818X_RX_CONF_MULTICAST;
printk(KERN_WARNING ">FIF_ALLMULTI");}
else {
priv->rx_conf &= ~RTL818X_RX_CONF_MULTICAST;
printk(KERN_WARNING ">not FIF_ALLMULTI");}
rtl818x_iowrite32_async(priv, &priv->map->RX_CONF,
priv->rx_conf);
printk(KERN_WARNING
"OUT>total_flags=%u,priv->rx_conf=%u",*total_flags,priv->rx_conf);
}
If you get different outputs also between your interfaces, please send
me all different outputs!
thanks :)
