This correction seems to work.

I read somewhere pci_free_consistent (in velocity_free_dma_rings) couldn't be use in a spin_lock.

Yup.

When I move velocity_free_rings outside the spin_lock, error desappeare but data transfert doesn't work after the mtu change.
When I add velocity_give_many_rx_descs all work.

I have updated http://userweb.kernel.org/~romieu/via-velocity/2.6.26-rc6/
accordingly. Can you check whether it is fine or not ?

Patch 0001 doesn't work,

if I don't make a mistake skb->len is not modified in skb_pad{,to}when the padding is applied. In this case, we need to attribute ETH_ZLEN to len.
