socat: Use c_ispeed and c_ospeed based upon libc
musl calls them __c_ispeed and __c_ospeed and we can not use get/set APIs because the get APIs will return the value from iflags and not from *speed element from termios struct Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com>

-Subject: [PATCH] Access c_ispeed and c_ospeed via APIs
+Subject: [PATCH] Use __c_ispeed and __c_ospeed on musl
-Use cfsetispeed(), cfsetospeed(), cfgetispeed, and cfgetospeed()
-instead of operating on c_ispeed and c_ospeed termios structure
-members directly because they are not guaranteed to exist on all
-libc implementations
+Original intention of these asserts is to find if termios structure
+is mapped correctly to locally define union, the get* APIs for
+baudrate would not do the right thing since they do not return the
+value from c_ospeed/c_ispeed but the value which is stored in iflag
+for baudrate.
+
+So we check if we are on Linux but not using glibc then we use
+__c_ispeed and __c_ospeed as defined in musl, however these are
+internal elements of structs it should not have been used this
+way.
