eth: tg3: silence the GCC 12 array-bounds warning
GCC 12 currently generates a rather inconsistent warning:
drivers/net/ethernet/broadcom/tg3.c:17795:51: warning: array subscript 5 is above array bounds of ‘struct tg3_napi[5]’ [-Warray-bounds]
17795 | struct tg3_napi *tnapi = &tp->napi[i];
| ~~~~~~~~^~~
i is guaranteed < tp->irq_max which in turn is either 1 or 5.
There are more loops like this one in the driver, but strangely
GCC 12 dislikes only this single one.
Silence this silliness for now.
