The array is sized to hold MVPP2_PORT_MAX_RXQ\nentries, and mvpp2_get_nrxqs() may return exactly that value. The\nper-CPU scheme then doubles it to nrxqs * 2, exceeding the array\nbounds.\n\nCheck that the hardware version is MVPP22 or newer and that the\nnumber of pools (nrxqs * 2) does not exceed MVPP2_BM_MAX_POOLS\nbefore switching to per-CPU mode.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE."
