The ethdev port id should be 16 bits now. This patch fixes the data
type of the variable for 'pid', changing from uint32_t to uint16_t.

The ethdev port id should be 16 bits now. This patch fixes the data
type of the variable for 'pid', changing from uint32_t to uint16_t.

We also need use RTE_BUILD_BUG_ON() to ensure that RTE_MAX_ETHPORTS
is less or equal to UINT16_MAX.

Actually the need is to check that we have room for an increment
after RTE_MAX_ETHPORTS, meaning RTE_MAX_ETHPORTS < UINT16_MAX.

As explained above, should check >=

This check is global for ethdev.
Please could you move it somewhere else?

If RTE_MAX_ETHPORTS is a maximum number of ports starting from
0 and loops are port_id < RTE_MAX_ETHPORTS, RTE_MAX_ETHPORTS
may be UINT16_MAX and it avoid 16-bit unsigned integer
overflow, but may be it is safer to cut one more port from
space do checks as above.

This is an ethdev value, so I would prefer having this test
inside librte_ethdev.

From: Yunjian Wang <wangyunjian@huawei.com>

The ethdev port id is 16 bits now. This patch fixes the data type
of the variable for 'pid', which changing from uint32_t to uint16_t.

RTE_MAX_ETHPORTS is the maximum number of ports, which customized by
the user. To avoid 16-bit unsigned integer overflow, the valid value
of RTE_MAX_ETHPORTS should be set from 0 to UINT16_MAX, and it is
safer to cut one more port from space.

So we use RTE_BUILD_BUG_ON() to ensure that RTE_MAX_ETHPORTS is less
to UINT16_MAX.

I don't understand why you add the compile check in several place.
We should just find one good place for checking RTE_MAX_ETHPORTS
at compilation time.

I suggest rte_eth_find_next() or rte_eth_dev_allocate().
Or maybe rte_eth_dev_is_valid_port().

Please choose only one.

That was my reaction, check once.
It doesn't even need to be inside a function, it can be anywhere.

OK, I will add the compile check in function rte_eth_dev_allocate().

From: Yunjian Wang <wangyunjian@huawei.com>

The ethdev port id is 16 bits now. This patch fixes the data type
of the variable for 'pid', which changing from uint32_t to uint16_t.

RTE_MAX_ETHPORTS is the maximum number of ports, which customized by
the user. To avoid 16-bit unsigned integer overflow, the valid value
of RTE_MAX_ETHPORTS should be set from 0 to UINT16_MAX, and it is
safer to cut one more port from space.

So we use RTE_BUILD_BUG_ON() to ensure that RTE_MAX_ETHPORTS is less
to UINT16_MAX.
