Subject: [PATCH] net: lan78xx: Disable TCP Segmentation Offload (TSO)
|
|
|
|
TSO seems to be having issues when packets are dropped and the
|
|
remote end uses Selective Acknowledge (SACK) to denote that
|
|
data is missing. The missing data is never resent, so the
|
|
connection eventually stalls.
|
|
|
|
There is a module parameter of enable_tso added to allow
|
|
further debugging without forcing a rebuild of the kernel.
