Comment (by lsoltero):
fixed.
910-01-add-support-for-mt7620.patch
modified rt2800_get_txwi_rxwi_size() to add a case statement for the
RT5390. The problem is that the logic added to the case tested for the
7620 but failed to set the values for txwi_size and rxwi_size when the
5390 was not associated with the 7620. So the full function should look
like
void rt2800_get_txwi_rxwi_size(struct rt2x00_dev *rt2x00dev,
unsigned short *txwi_size,
unsigned short *rxwi_size)
{
switch (rt2x00dev->chip.rt) {
case RT3593:
case RT3883:
*txwi_size = TXWI_DESC_SIZE_4WORDS;
*rxwi_size = RXWI_DESC_SIZE_5WORDS;
break;
case RT5390:
if ( rt2x00dev->chip.rf == RF7620 ) {
*txwi_size = TXWI_DESC_SIZE_5WORDS;
*rxwi_size = RXWI_DESC_SIZE_6WORDS;
} else {
// else clause missing in original patch.
*txwi_size = TXWI_DESC_SIZE_4WORDS;
*rxwi_size = RXWI_DESC_SIZE_4WORDS;
}
break;
case RT5592:
*txwi_size = TXWI_DESC_SIZE_5WORDS;
*rxwi_size = RXWI_DESC_SIZE_6WORDS;
break;
default:
*txwi_size = TXWI_DESC_SIZE_4WORDS;
*rxwi_size = RXWI_DESC_SIZE_4WORDS;
break;
}
}
here is a patch that fixes the problem
