Fixes issue where mlx4 driver stops receiving packets when mbuf
allocation fails in mlx4_rx_burst().
This issue appears to be caused because the code doesn't recycle the
existing mbuf to the sges array when mbuf allocation fails as is done
in the code right above it which handles (wc.status != IBV_WC_SUCCESS).
Copying the code from the above case fixes the issue.

Currently, 'rte_eth_dev_configure' fails on attempt to setup
max_rx_pkt_len > 2048 if no slaves was added to bonded device.
For example:
rte_eth_dev_attach("eth_bond0,slave=05:00.0,mode=l34", &id)
conf.rxmode.jumbo_frame = 1;
conf.rxmode.max_rx_pkt_len = 9000;
rte_eth_dev_configure(id, 1, 1, &conf)
Result:
EAL: Initializing pmd_bond for eth_bond0
EAL: Create bonded device eth_bond0 on port 4 in mode 2 on socket 0.
rte_eth_dev_configure: ethdev port_id=4 \
max_rx_pkt_len 9018 > max valid value 2048
It's expected that slaves will be added to bonded device inside
'rte_eth_dev_configure' and proper 'max_rx_pktlen' configured
for all of them.
Failure happens because of hardcoded low value of 'max_rx_pktlen'.
Increasing of this value to ETHER_MAX_JUMBO_FRAME_LEN will allow
above scenario (attach + configure).
It is important because it is the way OVS wants to work with
all DPDK devices (including virtual).
Changing the default hardcoded value makes no harm because
all the slaves' related code uses only 'candidate_max_rx_pktlen'
variable.

Some applications like OVS knows nothing about the
device type and wants to use same API to work with
all of them. But bond_pmd, unlike other pmds, requires
additional step (removing of all the slaves) before
closing the device.
In fact that bond_pmd automatically adds all the
devices from kvargs to bonding on configuration it
also should remove all of them on close.
This change is intended to have the same API for physical
and virtual devices. It allows us to handle virtual
devices in OVS in a common way.

When TSO is disabled we still have to calculate partial checksum if DF bit
if turned off. This is caused by firmware bug.
First of all, we must make sure that we are dealing with IPV4 packet.
If not, we will just skip further checking of this packet and move to
the next one.
If application will not set m2_len field, we assume we that it was Ethernet
frame because we have to look inside the packet to check for the DF flag.
To make it work properly, PMD is assuming that before sending
packet application called function rte_eth_tx_prepare().
