For the max rss size of PF may be up to 512, the max queue
number of single tc may be up to 512 too. For the total queue
numbers may be up to 1280, so the queue offset of each tc may

command, including extend tc size field from 10 bits to 11

Currently, the driver gets the max rss size from configuration
file when initialization. Both the PF and VF share the same
max rss size, and no more than 128.

For DEVICE_VERSION_V3, the max rss size for PF can be up to
512, so there is a new field in configuration file to store it,
the old filed is used for VF.

To be compatible with boards using old configure file, the PF
will use the old filed if the one is zero.

For the rss size may be larger than 256, so the type of
rss_indirection_tbl of struct hclge_vport should be changed to
u16 as well.

We observed that in the error case for batched send_subcrq_indirect() the
driver does not account for the partial success case. This caused Linux to
crash when free_map and pool index are inconsistent.

Driver needs to update the rx pools "available" count when some batched

This patch implements the ndo_xdp_xmit() net_device function which is
called when a packet is redirected to this driver using an
XDP_REDIRECT directive.

The function receives an array of xdp frames that it needs to xmit.
The TX queues that are used to xmit these frames are the XDP
queues used by the XDP_TX flow. Therefore a lock is added to synchronize
both flows (XDP_TX and XDP_REDIRECT).

This patch adds a partial support for the XDP_REDIRECT directive which
instructs the driver to pass the packet to an interface specified by the
program. The directive is passed to the driver by calling bpf_redirect()
or bpf_redirect_map() functions from the eBPF program.

To lay the ground for integration with the existing XDP TX
implementation the patch removes the redundant page ref count increase
in ena_xdp_xmit_frame() and then decrease in ena_clean_rx_irq(). Instead
it only DMA unmaps descriptors for which XDP TX or REDIRECT directive
was received.

The XDP Redirect support is still missing .ndo_xdp_xmit function
implementation, which allows to redirect packet to an ENA interface,
which would be added in a later patch.
