| | | | | | | | | | | | | | | | The following commit couldn't work if the RMCR is not set to 1. "net: sh_eth: fix the rxdesc pointer when rx descriptor empty happens" commit id 79fba9f51755c704c0a7d7b7f0df10874dc0a744 If RMCR is not set, the controller will clear the EDRRR after it received a frame. In this case, the driver doesn't need to fix the value of cur_rx/dirty_rx. The driver only needs it when the controll detects receive descriptors are empty.

| * net: sh_eth: fix skb_over_panic happenYoshihiro Shimoda2012-02-072-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When this GETHER controller received a large frame (about 1800 bytes or more), skb_over_panic() happened. This is because the previous driver set the RFLR to 0x1000 (4096 bytes) and the skb allocate size is smaller than 4096 bytes. So, the controller accepted such a frame. The controller can discard a large frame by the RFLR setting. So, the patch modifies the value of RFLR to mtu + ETH_HLEN + VLAN_HLEN + ETH_FCS_LEN.
