ks8851: Fix interpretation of rxlen field.
[ Upstream commit 14bc435ea54cb888409efb54fc6b76c13ef530e9 ]
According to the Datasheet (page 52):
15-12 Reserved
11-0 RXBC Receive Byte Count
This field indicates the present received frame byte size.
The code has a bug:
rxh = ks8851_rdreg32(ks, KS_RXFHSR);
rxstat = rxh & 0xffff;
rxlen = rxh >> 16; // BUG!!! 0xFFF mask should be applied
