But instead you prefer to convert array to function pointer to fix the struct size and make it independent from the configured 'RTE_MAX_ETHPORTS' config. And I assume current magic number for the 'ROC_NIX_INL_MEM_SZ' is calculated based on max memory requirement of the cn9k & cn10k: #define ROC_NIX_INL_MEM_SZ (1280) If so it can be better to describe 'ROC_NIX_INL_MEM_SZ' as what it is calculated from, like following but it is up to you: max(sizeof(x), sizeof(y)) ... >>> Bugzilla ID: 940 >>> Fixes: d26185716d3f ("net/cnxk: support outbound soft expiry >>> notification") Cc:stable@dpdk.org >>> >>> Reported-by: Wei Ling<weix.ling@intel.com> >>> Reported-by: Yu Jiang<yux.jiang@intel.com> >>> Signed-off-by: Vamsi Attunuru<vattunuru@marvell.com> >>> Signed-off-by: Srikanth Yalavarthi<syalavarthi@marvell.com> >>> --- >>> V2: Add bugzilla & reportee details, remove unused changes. >>> --- > ^ permalink raw reply [flat|nested] 9+ messages in thread
