3535 TOE功能如何全部打开

3535默认开启TOE功能。但通过ethtool查看，发现有些特性并没有开启，如下所示：
# ./ethtool -k eth0
Features for eth0:
rx-checksumming: off [fixed]
tx-checksumming: on
        tx-checksum-ipv4: on [fixed]
        tx-checksum-ip-generic: off [fixed]
        tx-checksum-ipv6: on [fixed]
        tx-checksum-fcoe-crc: off [fixed]
        tx-checksum-sctp: off [fixed]
scatter-gather: on
        tx-scatter-gather: on [fixed]
        tx-scatter-gather-fraglist: off [fixed]
tcp-segmentation-offload: off
        tx-tcp-segmentation: off [fixed]
        tx-tcp-ecn-segmentation: off [fixed]
        tx-tcp6-segmentation: off [fixed]
udp-fragmentation-offload: off [fixed]
generic-segmentation-offload: on
generic-receive-offload: on
large-receive-offload: off [fixed]
rx-vlan-offload: off [fixed]
tx-vlan-offload: off [fixed]
ntuple-filters: off [fixed]
receive-hashing: off [fixed]
highdma: on [fixed]
rx-vlan-filter: off [fixed]
vlan-challenged: off [fixed]
tx-lockless: off [fixed]
netns-local: off [fixed]
tx-gso-robust: off [fixed]
tx-fcoe-segmentation: off [fixed]
fcoe-mtu: off [fixed]
tx-nocache-copy: on
loopback: off [fixed]
rx-fcs: off [fixed]
rx-all: off [fixed]

一般来说，可以通过ethtool进行修改，海思貌似不能通过命令行修改。

各位，有什么好的修改办法吗？例如将rx-checksumming: off [fixed]置为on
