This is specified on data sheet only when LS is set must evaluate
RES bit very important patch.Whi say no here not undestand .Please
read Data sheet for more info.
Your patch ignores the following fact: the driver works with maximally
sized receive buffers to avoid fragmented packets - see git log for an
enlightning journey through the history of the r8169 driver.
Beyond blind datasheet compliance, have you been able to experience
FirstFrag = 0 or LastFrag = 0 receive descriptors with the current
in-kernel driver ?
