The talk

Hardware vendors want their devices to work on their clients’ sites, since these people are actually the important ones that bring profit to the company. Whatever OS they use, old or modern, even if they have to ignore support for some architectures. Portability and coding style is often very low priority when compared to performance and features.

Using the example of a network driver I maintain in the Linux kernel, I will describe the life of the code, from upstream development and maintenance (where the programming interfaces often change), to distributions (where backports make feature detection difficult), and to companies (where only performance and features matter).
