[PATCH] ibmveth fix failed addbuf
This patch fixes a bug that happens when the hypervisor can't add a buffer. The old code wrote IBM_VETH_INVALID_MAP into the free_map array, so next time the index was used, a ibmveth_assert() caught it and called BUG(). The patch writes the right value into the free_map array so that the index can be reused. Signed-off-by: Santiago Leon <santil@us.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
