With \"dev\" filter, a different code path is taken and\niplink_get() still uses only 16 KB buffer.\n\nThe size of 32768 is not very future-proof as NICs supporting 120-128 VFs\nare already in use so that single RTM_NEWLINK message in the dump can\nexceed 30000 bytes. But it's what rtnl_talk() and rtnl_dump_filter_l() use\nso let's be consistent. Once this proves insufficient, all three sizes\nshould be increased.\n\nSigned-off-by: Michal Kubecek <mkubecek@suse.cz>\n---\n ip/iplink.c | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)",
