pppd: Remove runtime kernel checks
|
|
|
|
On embedded system distributions the required kernel features for pppd are
|
|
more or less guaranteed to be present, so there is not much point in
|
|
performing runtime checks, it just increases the binary size.
|
|
|
|
This patch removes the runtime kernel feature checks.
