[ upstream commit 7c3c0d0f290cfc03dc0e75013af8035b450ee114 ]
GCC 12 raises the following warning:
../drivers/net/enetfec/enet_ethdev.c: In function
enetfec_rx_queue_setup:
../drivers/net/enetfec/enet_ethdev.c:473:9: error: array
subscript 1 is
above array bounds of uint32_t[1] {aka unsigned int[1]}
[-Werror=array-bounds]
473 | rte_write32(rte_cpu_to_le_32(fep->bd_addr_p_r[queue_idx]),
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
474 | (uint8_t *)fep->hw_baseaddr_v + ENETFEC_RD_START(queue_idx));
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from ../drivers/net/enetfec/enet_ethdev.c:9:
../drivers/net/enetfec/enet_ethdev.h:113:33: note: while referencing
bd_addr_p_r
113 | uint32_t bd_addr_p_r[ENETFEC_MAX_Q];
| ^~~~~~~~~~~
This driver properly announces that it only supports 1 rxq.
Silence this warning by adding an explicit check on the queue id.
