Start adding support to use the HWRM API.
Hardware Resource Manager or HWRM in short, is a set of API provided
by the firmware running in the ASIC to manage the various resources.
Initial commit just performs necessary HWRM queries for init, then
fails as before.
Now that struct bnxt is non-zero size, we can set dev_private_size
correctly.
The used HWRM calls so far:
bnxt_hwrm_func_qcaps:
This command returns capabilities of a function.
bnxt_hwrm_ver_get:
This function is called by a driver to determine the HWRM
interface version supported by the HWRM firmware, the
version of HWRM firmware implementation, the name of HWRM
firmware, the versions of other embedded firmwares, and
the names of other embedded firmwares, etc. Gets the
firmware version and interface specifications. Returns
an error if the firmware on the device is not supported
by the driver and ensures the response space is large
enough for the largest possible response.
bnxt_hwrm_queue_qportcfg:
This function is called by a driver to query queue
configuration of a port.

[Release Note Addition]

When using kernel PF and DPDK VF, when the PF driver finds the link
state changes, up -> down or down -> up, the driver will send a
message to VF by mailbox. This link state change may be
triggered by PHY disconnection/reconnection, user config change
like *ifconfig down/up* or interface parameter, like MTU change.
This patch enables the support of the mailbox interrupt,
so VF driver can receive the message for link up/down.
After VF receives this message, VF port need to be reset to
recover. This needs to be handled by the application so this patch
allows the app to register a reset callback so it can reset the VF port.

The value of these flags is 0, making them useless. Today, no example
application checks them on Rx, and only few drivers sets them and
silently give wrong packets to the application, which should not happen.
This patch removes the unused flags from rte_mbuf and their use in the
drivers. The i40e and fm10k are kept as they are today and should be
fixed to drop bad packets. The enic driver is managed by its maintainer
in another patch.

Testpmd application will crash in fclose() upon quit after running
the below command.
"sudo gdb --args ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf0 -n 4
--vdev 'eth_pcap0,tx_iface=enp1s0f1,rx_pcap=/tmp/test.pcap' --
--port-topology=chained -i"
The reason is, pcap vdev creation with tx stream type as "iface"
as in above command doesn't need member "dumpers" of
"struct tx_pcaps", hence will not have memory allocated for it.
It contains a garbage values, as local object of struct tx_pcaps
is not initialized to 0 inside rte_pmd_pcap_dev_init().
So calling pcap_dump_close() on dumper as part of eth_dev_stop()
is causing segfault in fclose().
Fix is to initialize local object of struct tx_pcaps to 0.
Also initialize local object of struct rx_pcaps to 0.
So during eth_dev_stop(), pcap_dump_close() will not be called if dumper
is NULL.

The offload flags variable (ol_flags) in rte_mbuf structure is 64-bits,

The Tx functions were in enic_ethdev.c and enic_main.c - files in which

Truncated packets occur on enic if an mbuf is not big enough to
receive it or there aren't enough mbufs if rx scatter is in use.
They show up as error packets but unlike other error packets (like
packets bad FCS) there are no nic drop counts incremented for them.
Truncated packets are calculated by subtracting hardware errors from
software errors. Note: this causes transient inaccuracies in the
ipackets count. Also, the length of truncated packets are counted
in ibytes even though truncated packets are dropped which can make
ibytes be slightly higher than it should be.
