To reduce the need of skb_linearize() calls, gso_max_segs of qeth net_devices had been limited according to the maximum number of qdio SBAL elements. But a gso segment cannot be larger than the mtu-size, while an SBAL element can contain up to 4096 bytes. The gso_max_segs limitation limits the maximum packet size given to the qeth driver. Performance measurements with tso-enabled qeth network interfaces and mtu-size 1500 showed, that the disadvantage of smaller packets is much more severe than the advantage of fewer skb_linearize() calls. This patch gets rid of the gso_max_segs limitations in the qeth driver. Signed-off-by:
