Because netdev_alloc_skb allocates "for RX", which uses different allocation flags internally and might do the wrong thing when memory is tight. Also, all skb free funtions are essentially the same, where dev_kfree_skb == kfree_skb by a macro definition, and what remains differs pretty much only in how it shows up in traces. They all call __kfree_skb internally. > > - Alex ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
