ice: support RDMA on 4+-port E830 devices
This patch updates the ice driver to support RDMA on E830 devices configured
with more than 4 ports. It modifies the port limit check to skip disabling
RDMA capabilities for E830 hardware.

[Severity: Medium]
Will this still log an inaccurate warning for E830 devices?
While this patch successfully preserves the RDMA capability for E830 hardware
with more than 4 ports, the code immediately following this block in
ice_recalc_port_limited_caps() remains:
/* print message only when processing device capabilities
* during initialization.
*/
if (caps == &hw->dev_caps.common_cap)
dev_info(ice_hw_to_dev(hw), "RDMA functionality is not available with the current device configuration.\n");
Because hw->dev_caps.num_funcs > 4 is true, will E830 devices incorrectly
trigger this warning during initialization even though RDMA remains enabled?
