commit a90d6a7450e0e1677f0a93d7eff3a8a3b3046053 Author: Jerzy Kasenberg <[email protected]> AuthorDate: Fri Feb 20 09:46:37 2026 +0100 net/lwip: Some LWIP options are now selectable in syscfg Package net/ip/lwip_mn/lwipopts provides way to have default configuration options for lwip. Now some options can be changed in syscfg. User can still use custome lwipopts.h if option packaged net/ip/lwip_mn/lwipopts is not added to dependencies.
