Copy just the topology section, and only when\nneeded. Reuse the buffer allocated for the read of the current topology.\n\nThis was found by kmemleak, with the following trace for each PF:\n    [<ffffffff8761044d>] kmemdup_noprof+0x1d/0x50\n    [<ffffffffc0a0a480>] ice_init_ddp_config+0x100/0x220 [ice]\n    [<ffffffffc0a0da7f>] ice_init_dev+0x6f/0x200 [ice]\n    [<ffffffffc0a0dc49>] ice_init+0x29/0x560 [ice]\n    [<ffffffffc0a10c1d>] ice_probe+0x21d/0x310 [ice]\n\nConstify ice_cfg_tx_topo() @buf parameter.\nThis cascades further down to few more functions."

Se hace que ice_cfg_tx_topo() sea constante y correcto, de modo que ice_init_tx_topology() pueda evitar copiar todo el blob de FW. Se copia solo la secci\u00f3n de topolog\u00eda y solo cuando es necesario. Se reutiliza el b\u00fafer asignado para la lectura de la topolog\u00eda actual. Esto fue encontrado por kmemleak, con el siguiente rastro para cada PF: [] kmemdup_noprof+0x1d/0x50 [] ice_init_ddp_config+0x100/0x220 [ice] [] ice_init_dev+0x6f/0x200 [ice] [] ice_init+0x29/0x560 [ice] [] ice_probe+0x21d/0x310 [ice] Par\u00e1metros de conversi\u00f3n de ice_cfg_tx_topo() @buf.
